Step-by-step installation of a towbar on a Chevrolet Niva with your own hands


Chevrolet Niva is one of the most popular domestic vehicles. This is greatly facilitated by its performance qualities. The machine is characterized as durable, which means that the installation of a towbar is quite possible. However, this may pose some difficulties.

Niva Chevrolet

The fact is that this device is specialized. It should be used mainly for towing not too heavy trailers. This constructive “gadget” is especially relevant in the summer season. But such a vehicle with a trailer places increased demands on its movement. Therefore, the choice of a towbar designed for a Chevrolet Niva must be approached very responsibly - for this brand of car it must have the appropriate standards.

Do-it-yourself towbar installation

The towing device is sold in a complete set, which consists of the towbar itself, a socket, wires, a cap on the ball, special nuts and screws (3 pieces each), 6 bolts, 6 spring washers and 6 regular graphite lubricants.

The basic set has everything you need, so there is no need to buy anything additional.

Before installing the towbar, the vehicle should be positioned so that you have access to its lower part. Also make sure there is good lighting so you can see all the mounting holes. Next you need to do the following:

  • clean the mounting area from dirt and remove the factory tape;
  • all elements intended for fastening must be lubricated with graphite grease;
  • Carefully insert the bolts into the pre-prepared holes and tighten the nuts tightly in order to secure the towbar well. First, a transverse rail is attached to the spar, and then a longitudinal one;
  • Lastly, install the removable ball.

The installation process of the towbar in photographs:

First you need to purchase a towbar. Choose a tow bar for your vehicle here. I have never seen a car on which you can install a towbar so quickly, within 10 minutes. Here, of course, we must pay tribute to AvtoVAZ. The standard body configuration already includes threaded holes for attaching a towbar, but they are sealed with tape. (In the photo, the taped areas are indicated by arrows).

You need to tear off the adhesive tape, place the towbar against the side members and the apron and tighten it with the mounting bolts (supplied), after lubricating them with graphite lubricant. That's it, the tow bar is in place!

Now you need to install the outlet. This will take much more time than installing a tow bar. For this:

  • Disassemble the socket: remove the stopper from engagement with the body
  • turn the contact pad counterclockwise
  • Strip the ends of the wires, connect them to the terminals used and tighten with screws. The procedure for connecting and pinout of the towbar socket is shown below:

  • Remember or better write down the order of connecting the wires by color. Insulate the harness or put a cambric or protective corrugated tube on it.
  • Assemble the socket. Coat the contact pad thickly with graphite lubricant.
  • Pull the harness through the hole in the bracket and install the socket. Lubricate the socket mounting bolts with graphite grease.

  • Disassemble the rear part of the luggage compartment
  • Remove the trim (6 screws). Remove the sound insulation.

    Near the area with the car body number, under the vibration-insulating layer, find a plug (in the photo, the area with the number and the plug are indicated by arrows).

    Take it off. Make a hole in it with a punch.

  • Reinstall the plug.
  • Pull the electrical wiring harness through the hole in it. Near the plug, make a branch of one of the wires that will go to the left rear light. In this case it is the yellow wire. The remaining 4 wires will go to the right lamp.
    Disassemble the right rear light casing (attached to two pistons). Disconnect the connector from it. Connect the towbar wiring harness.

    Remove the standard wiring for the right rear light from the corrugated tube. Strip the necessary wires, about 2-3 cm, and tin them with tin.

  • Measure the required length of the towbar harness. Cut off the excess and strip the ends of the wires by 3cm.
  • Tape the stripped ends of the towbar harness wires to a specific wire of the standard rear right light wiring. Solder the connection point. Make the “ground” wire under the terminal, install it on the stud, and tighten it with a nut (as shown in the photo).

    The procedure for connecting the towbar terminals to the rear lights is as follows:

    Towbar socketRight light wire colorLeft light wire color
    contact No. 1left turn—–blue-black
    contact No. 3weightto the body—–
    contact No. 4right turnblue—–
    contact No. 6stop signalred—–
    contact No. 7dimensionsbrown—–

    Insulate solder joints. Connect both strands together and put a corrugated tube on them. Wrap it with electrical tape in two or three places.

  • Connect the connector to the flashlight.
  • On the left side, do the same, connecting one single wire to the left turn light wire in the standard wiring. This wire will have to be extended first, because... its length is not enough. The splice area also needs to be soldered.
  • Check the functionality and correct connection of the wires on the towbar socket, alternately turning on the left-right turn, stop, and dimensions.
  • Assemble the rear part of the cabin.
  • Use the tow bar strictly for its intended purpose :))

    The towbar installation instructions/diagram are for informational purposes only. Since towbars from all manufacturers are different. AutoDels.com.ua is not responsible for any consequences when installing a tow bar. We recommend installing towbars only from specialists!

    Operational risks

    For this reason, towbars were not produced either, which provoked the growth of all kinds of handicraft industries.

    Their “products” suggested 2 types of do-it-yourself installation of a trailer hitch on a car:

    1. Attaching the towbar to the rear bumper guides;
    2. Attaching the trailer hitch to the side members and the car body.

    The photo shows how to install the trailer hitch on the bumper brackets

    In addition, the “handicraftsmen” also took into account the desires of the owners to equip their Nivas with gas cylinder equipment, which included installing a cylinder in the rear of the body. For this reason, the design of the trailer hitch attached to the side members looked rather unusual.

    Installing a towbar on a Niva 21214 with gas equipment provided only this option

    Note! Naturally, no one has carried out any dynamic tests of the trailer hitch, carried out according to GOST R 41.55-2005 standards. And car owners exposed their cars to danger, which often caused accidents.

    Towbar attachment points that have been torn out “with meat” are a natural result of incorrect installation

    Bumper towing options

    Before purchasing a towbar for a Chevrolet Niva, you need to familiarize yourself with the manufacturing companies and the varieties of this part.

    Among the companies that occupy leading positions in the production of towbars, it is worth highlighting such as “Bosol”, “Auto-Hack”, “Baltex”. Experienced motorists and specialists recommend choosing trailer hitches manufactured by these companies. The devices are characterized by high reliability and high-quality materials.

    Towbars for Chevrolet Niva are divided according to the design of the product into:

    • Removable.

    Easy to install and dismantle. Mounted with 2 or 4 bolts, which are easy to remove. You can often find models with a removable ball on sale.

    • Fixed.

    They are a one-piece design. Installed on a reinforced car bumper. They are welded to the side members or attached to massive bolts.

    • Quick release.

    Often equipped with a folding mechanism. The ball is removed and stored separately from the trailer hitch. Used for transporting light loads in a trailer.

    On the old-style Niva there are no standard mounting points for the tow bar. Experts do not recommend making special holes for mounting the trailer hitch yourself. In addition, it is impossible to find models of towbars for such cars on sale, and homemade towing devices do not have the proper quality.

    After selecting a suitable towbar, we proceed to install the trailer hitch on the vehicle ourselves.

    Recommendations for using the tow bar

    If you have correctly installed the towbar on the Niva, you should adhere to the following recommendations for using the trailer hitch:

    • It is prohibited to tow cargo weighing more than 1300 kg.
    • It is necessary to adhere to a certain speed limit when towing a trailer (no more than 90 km/h).
    • The load on the coupling ball should not exceed 50 kg.
    • At each vehicle maintenance, it is necessary to tighten the connecting threads.
    • If the load extends beyond the trailer by 1 meter at the front or rear, or 40 cm from the outer edge of the side light, it must be marked with special identification marks.

    You should also adhere to the rules for placing cargo in a trailer. It should be evenly distributed, that is, the center of gravity should be above the axle (if we are talking about a single-axle trailer) or between the axles (if you are using a two-axle model).

    These rules should not be neglected, since in a situation where the load is shifted forward, the load on the coupling device and the rear of the machine will increase, which will lead to poor traction with the road surface. It is also impossible to allow a shift back, otherwise the rear part of the car will rise, which will also worsen the vehicle’s handling.

    Varieties

    It is not difficult to install the metal component of the tow bar, that is, this entire structure, on the car. Plus, some cars come from the factory with a trailer hitch, that is, a towing device (this is our tow bar, but you already know that).

    But you need to connect the towbar socket to the car. Otherwise, it will be impossible to connect the trailer. More precisely, you will perform a mechanical connection with a special lock. Only the trailer lights will not be able to function. If you drive out onto the road in this condition, you risk receiving a serious fine.

    When buying a trailer plug or a car towbar socket, be guided by what type of connector they have. By purchasing everything at the same time, there will be no problems with the choice. And when purchased separately, the connector may turn out to be different.

    In general, towbar sockets are of two types:

    7-pin. This is a European standard scheme that is widely used on domestic cars and our trailers. The connection is quite simple, which is why this type of wiring has gained such popularity;

    13-pin or 13-pin socket. A variation designed to connect a car's towbar to trailers such as a motor home. That is, towed devices that need to provide not only connection to lighting devices, unlike 7-pin ones.

    Since in most cases a conventional trailer is installed for transporting goods, it is logical to use 7-pin connectors.

    But don't be alarmed if the factory trailer plug or the standard towbar socket differ in the number of contacts. For such situations, a special adapter or adapter is provided according to the 7/13 or 13/7 scheme. Accordingly, if the pinout is the same, you won’t have to use any additional adapters.

    What to choose

    In this article, we specifically did not describe the technical characteristics of each product. The thing is that for the average person this information will be like an explosion in the head. All the numbers are intertwined there and you can get confused. We can give you advice on how to proceed easier.

    Ask yourself what do you want from a tow bar? What will you carry on it?

    If you are looking for a budget model, this is definitely the Trailer! One of the advantages is the price from 2500 rubles. and technical characteristics, the disadvantages are the short-lived coating

    We recommend: What happens if you pour sugar into the gas tank of a car?

    The highest quality, toughest and most durable towbar is the Bosal VFM tow bar. But the price also corresponds, starting from 3200 rubles.

    The average option, which combines good technical performance, reliability and durability, is Leader Plus. This manufacturer offers the maximum range of types of balls. The line includes a towbar for gas-cylinder equipment. Prices start from 2500 rubles.

    Selecting a trailer hitch

    Is there an option for installing towbars on Nivas if the car originally came from the factory without one? Yes. These domestic crossovers have special holes, so the trailer hitch is mounted in standard places. But you will also need to drill a few additional holes. Now look specifically at your car.

    Niva car owners are offered the installation of several trailer hitch options:

    • non-removable or non-removable, in which the hook or coupling ball is welded to the base;
    • conditionally removable, fastened with several bolts;
    • quick-release, having a slightly protruding coupling for fixation, which allows you to store the hook with the ball separately;
    • quick-release with a vertical type of fastening, where the hook is pulled down and the fasteners are not visible;

    I will say right away that a removable ball is more preferable for me, since this design allows you to use the trailer hitch only when necessary. Moreover, it is better to take quick-release devices, because unscrewing several bolts will take quite a lot of time.

    For VAZ Niva 4×4, they usually prefer to choose the simplest towbar options. They are inexpensive and can be purchased for several thousand rubles. Although this has its drawbacks.

    Alternative trailer hitch options

    There are alternative solutions that I would like to discuss with you.

    • Reinforced bumper with towbar. Nowadays, the Chevrolet Niva towbar with bumper protection is very popular. But no one is stopping you from installing it on the classic Niva. This is a ready-made bumper with a trailer hitch mounted into it. Products from Bosal (Bosal) or RIF will cost about 30 thousand rubles. This cost is justified because you get a bumper with a powerful gate and reinforcement, providing a high degree of rigidity and resistance to loads. Allows you to carry heavier loads. In this case, installation is carried out on conventional crossover body brackets and no modification is required;
    • Square towbar. Another option for the rear bumper. It costs about 2 times less than the previous trailer hitch. But you will need to buy a ball joint separately. It is in great demand due to price, ease of use and load-bearing capacity. And it looks quite original compared to standard towbars. Just look at the numbers indicated on the trailer hitch. They indicate permissible traction loads and additionally help to make sure that what you are looking at is not a fake.

    In general, the topic of the power bumper for the Niva deserves special attention.

    Each towbar comes with a connection and installation diagram; the kit includes a towbar socket and instructions on how to connect the socket and all electrical components.

    Some people prefer to assemble the towbar with their own hands, relying on drawings, photos and video instructions. Personally, my opinion is that this is not the best option. To assemble a full-fledged high-quality tow bar, you need to take into account all dimensions, select high-quality materials, use the appropriate wires for electrical equipment, and so on. And how much does it cost to assemble a homemade trailer hitch? If it’s high quality and reliable, then it’s about the same as a standard factory tow bar. This is an imaginary saving of money. The price will be the same, but the quality of construction will not. Plus, it is more difficult to register a homemade towbar; problems may arise during registration.

    I advise you to first familiarize yourself with whether it is possible to install a trailer hitch and what the traffic regulations now say about this.

    Requirements for a towbar on a Niva Cheverol

    The proprietary device that is planned to be installed on this car model must meet all the necessary standards. Typically, before it goes on sale, it undergoes tests that check metal fatigue and all important loads.

    Before the towbar is installed on the Chevrolet Niva, you need to ensure that it meets the following requirements:

    1. Be sure to purchase an original tow hitch.
    2. Towing weighing more than 1300 kg is not allowed.
    3. When traveling, you must not exceed a speed of more than 90 km/h.
    4. It is imperative to monitor the load on the coupling ball - it should not exceed 50 kg.
    5. With each subsequent maintenance, tightening of thread connections is necessary - it is better to do this at a service station.

    Fine for a towbar installed incorrectly

    It is considered a violation to purchase a “homemade” tow bar and then install it yourself. The law also prohibits the use of trailer vehicles without the appropriate documentation - certificates, etc. If this is discovered during the operation of the vehicle, in accordance with the current Administrative Legal Code, the driver risks earning a fine of 500 rubles.

    A similar fine in the same amount will be imposed if the towbar installed on the Chevrolet Niva turns out to be faulty. The driver is obliged to monitor the condition of this device, since this can lead not only to a fine, but also to the immediate sending of the car to the impound lot until the problem is resolved.

    Connecting the towbar socket

    When connecting the towbar socket, you need to know the wiring diagram of your car. Usually it has 7 contacts, 6 of which are in a circle and 1 in the middle. But please note that in imported trailers there are 9 such contacts, of which 2 more are designed to provide additional lighting and operation of household appliances. Before connecting the equipment, check that there are no burnt contacts anywhere and disconnect the car battery. Further:

    • strip the insulation on the wiring of the rear headlight;
    • Carefully solder one of the wires to the contact in the socket using the pinout diagram, then solder the next 6 contacts;
    • carefully wrap the wire insertion points with insulating tape;
    • return the headlamp to its place and connect the battery.

    Once completed, check all of the vehicle's lights.

    Direct connection diagrams

    If the towbar and trailer of a passenger car (and truck) are equipped with the appropriate connectors, then the electrical connection diagram will not be needed at all, since you just need to insert the socket into the socket.

    When the car is not equipped with a modern electronic control unit. Thanks to this, electrical wires can be directly connected to existing electrical circuits. That is, the wires that come from the connector are connected to those connected to the rear lighting equipment.

    Electrical connection

    An electrical connection is necessary for the operation of additional lighting on the trailer. For this purpose, a 7-pin socket is used, which is supplied with the towbar.

    The socket connection diagram is in the towbar instructions and looks like this:

    1. Left turn signal.
    2. Fog lamp.
    3. Weight.
    4. Right turn signal.
    5. Reverse.
    6. Brake signal.
    7. Parking lights.

    Connecting the socket to the wiring is carried out according to the following algorithm:

    1. The rear headlight is removed and the insulation on its wiring is stripped.
    2. The wires are soldered in accordance with the pinout diagram.
    3. The places where the wires are inserted are wrapped with electrical tape.
    4. The headlight is installed in place.

    After completing the work on connecting the socket, check the functionality of the trailer lights.

    Comments 11

    I remember I came to buy a trailer. The towbar was in the trunk. While my wife was filling out the paperwork, I installed the towbar. I connected it according to his instructions - it turned out to be wrong. I connected it according to the trailer instructions - everything works. They could have messed up the wiring in the trailer - I don't know.

    By the way, I didn’t know about the rubber plug; I ran the wiring through the left air duct. It needs to be redone.

    In principle, they’ve already suggested it, but I’ll add some little additions for completeness...

    The colors in the car are:

    Driver's side light Black - Red foot Green reverse Orange/black rear fog lights Yellow dimensions Blue-black left turn

    Passenger side light Blue is a right turn

    The right turn signal cord stretches through the standard rubber bands to the lights, remove the rubber band, thread the connector, wind up the wire, insert the connector into the headlight, wrap it around the rubber band with electrical tape to the standard wiring, and return the rubber band to its place, under the plastic trim across the trunk, secure the blue wire with electrical tape and that’s it ...

    In the towbar socket the numbers are signed, but... 1) left side 2) rear PTF 3) weight 4) right side 5) reverse 6) feet 7) dimensions

    I recommend starting with the marker pin (in the center of the socket)

    I pull the entire tourniquet outward in a different way than in the picture. a) On the driver’s side, inside the wing, at the canopy, remove the air duct clapper, swaying upwards and pulling... b) Spray everything with water... c) Having wound all the wires at the end with electrical tape, pull the cable through a thin round elastic band, where the black and yellow wires pass d)

    We intercept it from below under the elastic band and pull it all back into the cabin. This way we pull the harness through the rubber band and do not interfere with the reinstallation of the flapper valve. If the valve is not installed, then there will be an incredible amount of dust in the cabin(!) e) We tie 60 centimeters to a broaching wire and push it back down, closer to ourselves, sitting in the trunk, the harness passes in the area of ​​​​the ventilation in the bumper, but closer to the driver ( you need to get there, it’s a matter of skill and luck) e)

    The emergence of a new Niva

    Everything changed with the appearance of a new model in the AvtoVAZ lineup - the Chevrolet Niva:

    1. The manufacturer has provided attachment points for the trailer hitch;
    2. They have been reinforced and equipped with threaded connections;
    3. For operation without a towbar, the attachment points were initially sealed with special tape.

    Factory instructions allowed towing trailers weighing up to 1300 tons

    Note! The automaker entered into agreements with trailer hitch manufacturers, which led to the unification of parts for the coupling device, thereby protecting the cars and their owners. This applies not only to the Chevrolet family - installing a towbar on a Priora station wagon has also become safer.

    Thanks to this, every owner of new AvtoVAZ cars can independently purchase and install a trailer hitch kit. In addition to towing, the towbar often serves as additional protection for the underbody, as well as making stickers for the headlights, protecting the glass from flying stones.

    Installation instructions

    Before installing a tow bar on a Chevrolet Niva with your own hands, you need to prepare the car:

    • Place the car on an overpass or inspection hole.
    • De-energize the vehicle.
    • Remove the luggage compartment trim.

    Next, for successful installation, you need to find the mounting points on the bracket. To do this, the trailer hitch is applied to the spar, then the mounting holes are found. They are sealed with special tape; after removing it, the car enthusiast can begin installation:

    1. The fasteners are lubricated with graphite grease supplied with the trailer hitch.
    2. The product is applied to the rail from behind, bolts are inserted into the holes and secured with nuts. The operation is performed in the following sequence: initially, a transverse nut is installed, intended for mounting the trailer hitch mount, then this rail is connected to the longitudinal one.
    3. A removable ball is installed, and a hook to which the trailer is attached.

    After completing the installation of the traction hitch, proceed to connecting the electrical outlet.

    Installing the tow bar

    The standard trailer hitch set for the Chevrolet Niva includes:

    • set of wires and socket;
    • screws and nuts (3 pieces each);
    • 6 bolts;
    • 6 regular washers and 6 spring washers;
    • ball cap;
    • graphite lubricant.

    Having prepared everything you need, position the car so that you have access to the underside of the car and perform the following steps:

    1. Place the towbar against the mounting location to determine where the mounting holes are located.
    2. Clean the mounting points from dirt and remove the factory tape from them.

    Healthy! There is no need to remove the bumper, which significantly speeds up the installation process.

    1. Lubricate all fasteners with graphite grease.
    2. Attach the hitch to the spar and apron, after which you need to insert the bolts into the holes and secure them tightly with nuts in the following sequence: first, attach the transverse beam, which is attached to the spar (inside the rear bumper), then this rail is connected to the longitudinal one.
    3. Install the removable ball.

    This completes the mechanical installation. Now you need to connect the electronics responsible for the light elements of the trailer.

    Features of the socket connection

    To connect the towbar to the vehicle's electrical wiring, we recommend using stranded copper wire. The ideal option is a wire in which each core has a cross-section of at least 1.5 square meters. mm. The wire must have a double layer of insulation.

    After connecting the trailer according to our diagram and checking the functionality of its lighting equipment, it is advisable to take care of protecting the internal elements of the outlet from moisture. It would be a good idea to use graphite lubricant, which will also prevent oxidation of the contacts.

    Manuals→VAZ→21213 (Niva) Electrical wiring for trailer electrical equipment

    general information

    Several types of towbar connectors are available with different terminal locations in them. The most common is the 7-pin connector, which provides two additional circuits, typically used to supply power to the reversing lights and electric trailer brakes.

    When equipping a towbar, it may be necessary to replace the previous turn signal switch with a more powerful one in order to maintain the flashing frequency of the signal lights specified in the traffic regulations adopted in a particular region. Authorities in some regions also require the mandatory installation of turn signal repeaters on the instrument panel.

    If the towbar connector socket does not match the size of the plug installed on the trailer, you should purchase one of the suitable adapter adapters available (see accompanying illustration).

    Trailer plug installation

    To equip a trailer with a towbar connector, the following is required (at a minimum): a plug corresponding to the connector socket on the vehicle, a 7-core flexible cable and insulated connectors for connecting the wires.

    The procedure for installing a plug on a trailer is similar to that for installing a receptacle socket on a car, taking into account the points listed below.

    EXECUTION ORDER
    1. Connect the trailer electrical wiring to the connector plug in accordance with the generally accepted color coding standard. Follow the connector manufacturer's instructions. If the free length of the trailer wiring harness is not enough, extend the harness using 7-conductor flexible cable and insulated wire connectors.
    2. If the color scheme of the trailer wiring does not correspond to the generally accepted standard, identify each of the wires by: Finding the trailer ground wire;
    3. Connect a jumper wire from the negative terminal of the 12-volt battery to the ground wire;
    4. Connect the jumper wire to the positive terminal of the battery and connect each of the trailer harness wires to it in turn. Make a note of the color of each wire and the device (signal light/brake) that was activated when you connected it.
    • After installation is complete, connect the plug to the towbar socket on the vehicle to check that the connector components are properly mated.

    By installing a towbar on a Chevrolet Niva, the motorist has the opportunity to transport trailers and other vehicles. The manufacturing plant of this model intends to make similar modifications to the design of the car, therefore it equips the car with standard places for attaching the trailer hitch. Installing a towing hitch has some nuances.

    I thought for a long time which tow bar to buy, new or used. From time to time I looked at advertisements for the sale of used trailer hitches on various websites. There weren’t many of them, and the ones that came across, I didn’t like the design. I started to consider purchasing a new trailer hitch. It also has its own nuances: cheap and “not beautiful” or beautiful, but expensive) In the end, after looking at photos of the Niva with various towbars, the choice fell on bosal.

    Price tag in the city: 2690 rubles - 1207-H (not removable ball); 2740r - 1207-A (with removable ball). As you already understand, I purchased a bosal hitch with a removable ball. For a difference of 50 rubles, I can remove the ball at any time (for various reasons) and move on, or not remove it. The towbar was delivered to order, on the 4th day. Go.

    This box contained fasteners, a socket, a cap, and instructions. I don’t know how things work with the configuration of towbars from other manufacturers, but here is a complete set of fasteners, including a socket, 5-wire wires and a cap. Overall I liked it!

    Freeing up space for creation. Subsequently, we had to remove the paneling completely, because... I had to drill a hole on the right side too

    We attach the trailer hitch to the bumper brackets to mark the holes in the floor cross member

    The holes are already drilled* But in order to drill the holes I had to remove the rod halfway. On the left we unscrew the bolt completely, and on the right we “loosen it”. As a result, the rod hangs and does not prevent us from drilling holes.

    Holes in the process I first drilled with a 6 drill from the bottom, then on both sides with drills: 8.10 and then, from above, with a 16 drill + processing the hole with a roller cutter, for a diameter of 16.5 mm. And all for the purpose of getting the bushings through.

    We lower it carefully, because the length of the bushing is less than the internal thickness of the cross member, and we can simply lose the bushing in it. Getting it is certainly not a problem, but it will waste time.

    Bolt for additional fastening of the bracket to the body. Drilling must be done carefully, because We may subsequently rest the nut against the towing eye mounting bolt. You can, of course, drill a hole closer to the “standard” bolt securing the bracket to the spar, but then the additional bolt won’t be of much use. Or vice versa, closer to the rear apron, but apparently there is no additional patch there, which means the body metal there is thinner. Everyone has their own taste and color, but personally I approached the location of the additional bolt with such arguments.

    The drilling stage is the same, from below with a long drill 6, after the drill 9...12 and on top 16 + a roller cutter (under the sleeve)

    On the left side, in order to drill a hole, I had to “throw off” the muffler from the rubber band.

    Wiring I inserted the harness through the elastic band at the bottom of the apron, which I had previously drilled. The cable itself was laid inside the apron and led to the left headlight.
