As a rule, every motorist is faced with the need to transport cargo that cannot be put in the trunk - a bicycle, a motor boat, building materials, and finally potatoes from the garden.
Therefore, the problem of choosing, purchasing and installing a tow bar for attaching a trailer for moving cargo is familiar to many. There is a huge selection of trailer hitches for Vesta brand vehicles on sale. The body model (sedan, station wagon, SV Cross) is not of fundamental importance.
You can figure it out yourself, or you can resort to the help of employees of specialized stores (leave a request and we will call you back) or centers for installing towbars. They will help you find the right option, meeting all the requirements of your car manufacturer.
Installing a towbar on Vesta is not tuning the car. Therefore, if you have a certificate and passport, registration of the device with the traffic police is not required.
Installation of tow bar on LADA Vesta SW
The Lada Vesta SV tow bar is an irreplaceable thing in any car that can help out in difficult times. But this is only if you use the trailer at least periodically. If the trunk is enough for you to transport things, then there is no point in spending extra money and bothering with its installation. The towbar can be installed on any car. Manufacturers develop special designs that are adapted to specific models. Today, including for LADA Vesta SW, you can easily purchase this design and install it on your car within a short time.
Connection
The connection is made through a special electrical module - a matching unit (smart connector).
Turn off the ignition, disconnect the earth wire terminal from the battery.
Connect the electrical module type Smart Connect KA.SC.7.1, supplied with the trailer hitch kit, in accordance with the instructions supplied with the module.
The matching block can be made independently based on conventional 4-pin relays:
Almost all the necessary contacts for connection can be found in the rear light area (see Lada Vesta electrical diagrams), or use a multimeter). Additionally, you just have to run the wire from the battery through the fuse along the left side (photo author).
Advantages of installing and using a tow bar
An installed towbar on a car provides certain advantages due to the fact that a small trailer can be used:
- the possibility of using the car is expanding;
- the machine can be used as a tractor;
- can transport large cargo;
- significant volumes of cargo can be transported at one time;
- The towbar is made from anti-corrosion and high-strength metal that can withstand heavy loads;
- A number of design models are offered, which differ in some characteristics and type of execution.
The process of installing the structure on a car is quite simple. However, you need to know a number of details about its installation and partial disassembly of the car itself. These devices are supplied with all the necessary parts for installation of the structure.
Design options
At the moment, the selection of towbars for SV Cross is small. They are conventionally divided into two groups:
- removable – can be removed if not needed, which will not affect the appearance of the car;
- non-removable – they are rigidly mounted to the body and remain on it permanently.

Since this car model is quite new, there are still few manufacturers of this part, since companies have not yet managed to implement a full-fledged production of components and parts for Vesta.
You can purchase the original device from official AVTOVAZ dealers. There, the cost of a towbar is approximately 7-7.5 thousand rubles . In addition to the original, it offers its own analogue - a removable tow bar, the price of which is about 3-3.5 thousand rubles . Among the major manufacturers, the Russian company AvtoS began producing designs for Vesta SW. The model has already gone into production, but the price needs to be clarified with the distributors. There are also several foreign companies that have already partially launched the production of components for this car.
The following structural models can be installed on Vesta:
- A flange-type device is considered the best option for Vesta, but only if there is a special seat for uniform traction force and load distribution.
- Models with rigid fixation cost less and are easy to install and functional. But they have an unaesthetic appearance, and fastening occurs using bolts or welding.
- Removable hitch ball devices have a removable top and are virtually invisible. The model is stable and reliable, but costs much more than other analogues.
- You can also find American-type towbars on the market, but they are rarely chosen. This is due to installation difficulties, the dimensions of the ball are slightly different, there is a difference in the seat, and the socket does not match.
Many experts recommend installing removable models. Even though they are the most expensive, they can always be removed so as not to spoil the appearance of the car. But most drivers are not particularly concerned about the presence of a constantly peeking towbar.
Principle of operation
The electrics of the towbar and the BSF must be connected in parallel, using high-quality crimp clips. Please note that the connection is made directly to the matching unit, and not through the socket of your car towbar.
The BSF is connected to the battery or power supply. In this case, the principle of its operation will be as follows:
- smart connect receives relevant information from the on-board computer system;
- the matching block transfers a uniform and dosed load to the necessary consumers, that is, the trailer's lighting equipment.
Here we need to add one important point. You cannot take the universal BSF if the car has the so-called trailer towing mode.
Here, to connect the towbar to the towed vehicle (connection of the towbar and trailer, in other words), you will need an original block. Otherwise, the vehicle will not be able to control and monitor the electrical equipment of the trailer using its ECU.
Among the popular block models, users note the following:
Their price is reasonable, that is, there will be no significant costs for operating the trailer. Knowing the item number of the product, you can easily order for delivery online. Choose the purchase method yourself. The main thing is that the BSF matches your car model.
Equipment
BSF has a built-in protection system, with the help of which it is possible to protect the electrical network from overvoltages and short circuits.
When installing the unit, your on-board computer will function normally. That is, it will not start reporting new connected devices or giving any errors.
When choosing a Smart Connect device, pay attention to its configuration. She may be:
There is no special or urgent need for expanded equipment, and it costs more. Personally, I installed a more functional model. For this you will receive, in addition to the basic functions, protection against theft and control over the entire electrical circuit of the towed vehicle.
Basic criteria for selecting a part
When choosing a device for Vesta SW, you need to take into account the types of coupling devices and some other nuances:
- connectors (round or rectangular), trailer socket;
- maximum load on the structure and fasteners, permissible trailer weight;
- load class - must be 1 or 2, which can withstand a load of 900-1500 kg .

It is also worth paying attention to the condition of the paintwork. There should be no scratches, chips, gaps or any defects. Otherwise, moisture will enter the metal, which will lead to corrosion.
Required
Towbar
(original catalog numbers):
- Lada Vesta sedan (article 99999218007282), price about 6800 rubles;
- Lada Vesta SW/SW Cross (article 99999218107282), price about 7,000 rubles;
Control unit (coordination)
99999215007182 Smart Connect KA.SC.7.1, price about 2900 rubles.
The matching unit is an unloading device that ensures uninterrupted operation of the vehicle and trailer electronics. The equipment protects the vehicle wiring from overloads - as a result, the vehicle’s on-board diagnostic system does not detect the connection of additional devices to the vehicle’s electrical network, and operates in normal mode.
Where can I buy?
Installing a tow bar
Installation of the structure is carried out as follows:
- The rear bumper is removed.
It is very important to know how the bolts were installed and to understand how the structure itself is removed from the clamps. The main part of the hitch is mounted under the bumper.
- The rear spar plugs are removed. Then the power frame is mounted.
- Open spaces serve as a place for attaching the traction structure.
- The bolts are carefully tightened.
- The bumper is mounted back.
- Install the towbar ball in a standard place, tighten the nuts.
The trailer hitch control unit is included with the traction device. Almost all wires are connected to the rear lights; you just need to run the wire to the battery through the fuse on the starboard side. This work is best left to a competent electrician.
As you can see, the process is quite simple. But you can achieve a good result only if you have certain skills and confidence that you can handle it. Otherwise, it is better to contact specialists.
Connection
To connect, you can use the video instructions and follow the recommendations below.
- The BSF is connected to the car battery;
- The oil pressure sensor, starter, car fuel valve and the on-board computer of your car must be connected to the smart connect;
- They remove the loading panels, prepare a set of wiring, check the operation of the running lights and the trailer brake light;
- The smart connect is installed according to the diagram provided by the manufacturer. It will look approximately as shown in the image.
It’s up to you to install BSF yourself or entrust the installation to professionals. Advice from me personally. If you do not have experience or skills in working with car wiring, or simply do not have time to do it, contact a specialist. They can carry out the entire range of work, from selecting a tow bar and trailer, to selecting a suitable unit and connecting all these devices into a single circuit.

How to check if everything is done correctly
For installation and connection of the structure, only technological holes are used. If they are not available, you can make them in the bottom yourself using special equipment. All elements are mounted and adjusted to the holes, everything is carefully checked, since minimal misalignment can lead to rapid wear of both the towbar itself and its wiring.
The fasteners must be tightened well to avoid possible displacement. Before using a coupling structure, it is tested to determine whether the coupling device can withstand the permissible load. Before installation, it is recommended that all holes and joints be treated with a grease-type lubricant; a plate-type compound for processing the coupling ball is best suited. Before installing the ball itself, it must be covered with a cap.

Popular solutions
First, I’ll say a few more words about the installation. Be sure to buy good quality grease, which must be used to treat all joints during installation. This will not only simplify installation, but will also allow you to disassemble the structure in the future without any problems.
Also apply lubricant to the coupling ball, the types of which you can find here. It is better to install a protective cap over the ball treated with lubricant. It will prevent the adhesion of dirt and dust, and will also keep your hands clean when removing and installing the ball for connecting the trailer to the Lada Vesta.
Now regarding specific towbars. In Russia, Vesta owners actively buy products from Leader Plus and Bosal. I do not limit you to these companies at all, but I still advise you to take a closer look at them. Let's look at a few towbars.
Reviews
| Positive | Negative |
| I purchased the original design from the officials and am absolutely satisfied with everything. They were also installed at a company service station. In general, everything cost me about 12 thousand, but everything was done quickly and efficiently. There is not a single scratch on the bumper, everything is holding tight. I use the trailer several times a week to transport goods. The trip to the forest with tents was very comfortable - there was nothing unnecessary in the car. | I recently received the ordered trailer. Everything is fine, but there are not enough threaded plates that are mounted in the side members. I didn’t check everything right away and had to use large nuts and washers during installation. There may be nothing wrong with this, but now you will have to constantly check the condition of the structure and operate the trailer very carefully. |
| I purchased the model only because it had a complete connection kit. However, as it turned out, everything is not so simple. The connection block must be selected wisely, since not everything is so simple in Vesta. | I ordered a towbar via the Internet, but it arrived without standard electrics. How is this possible? Now I don't know what to do. |
| I didn’t want to install a tow bar, but we often go out of town on weekend vacations, so I took the plunge. Everything is great! There is nothing unnecessary in the car, everything is in the trunk and in the trailer. Necessary and even more. Now we can carry with us not only tents, but also mattresses, a folding table and chairs. | I ended up with a batch of towbars that no one checked. As it turned out, the party was very problematic. Either there are no sockets, then there are no wires, then there are no bolts. I received a set without plates. As a result, we had to wait almost two weeks for them to be delivered. |
| I recommend purchasing parts only from official representatives. And install the towbar itself from them. I am pleased with the work of the specialists and the quality of the purchased device. | I decided to purchase it online because I live quite far from a big city and didn’t want to go there myself. I contacted several stores with a request to provide a certificate. But in the end no one showed it. Now I doubt the quality of the products, so I will contact the officials. I'd rather pay more, but I'll be calm. |
| I purchased the trailer on the market and the towbar from the officials. I installed it myself, no problems. Everything is quite simple and fast. There were problems with the connection, but the electrician quickly solved them. The trailer is small, but it’s enough for me to bring vegetables and fruits from the dacha. | I contacted a private service station to install a tow bar. Not only did they not figure out how to connect the control unit, but they also did not remove the bumper when installing the structure. As a result, you need to buy a new unit and the bumper is quite scratched, which will have to be repainted by the service. |

Many car owners cannot imagine their car without a towbar and therefore want to quickly equip their recently acquired Lada Vesta with this device. The choice of this device is carried out individually for each specific car brand. There is a wide range of towbars for Vesta on the market, allowing you to choose the most suitable one in terms of type, quality and price. Installation of the unit can be done either in a car service center or with your own hands.
Whether a tow bar is needed on the LADA Vesta SW or not is up to everyone to decide for themselves
Everyone can figure out how to install the structure correctly, but it is better to entrust this matter to specialists.
For those who only drive around the city and do not transport a lot of cargo, it is not needed at all. Vesta has a fairly large trunk, which is quite enough for most car owners. But if you have a summer house, from which you carry a lot of products, and like to relax in nature, then you should install a towbar.
If you doubt it, then buy a removable towbar and the problem is solved. This is the optimal solution, which is distinguished by reliability and quality. However, it can be removed, and it will not spoil the appearance of the car.
