Instructions for installing a new panel

If you want to replace a low tidy with a more advanced, high one, then in any case you will have to change the entire center console.

Removal and installation instructions look like this:

First, you need to turn off the power to the on-board network; to do this, disconnect the battery, remove the steering wheel, as well as the steering column switches and the ignition switch. You will also need to disconnect the ignition relay.
Next, unscrew the two bolts that secure the control panel visor and remove it.
Now you need to compress the spring and remove the shield itself from the center console. Disconnect all wires and connectors connected to the dash, including the speedometer cable, the econometer hose, and the odometer cable. After this, the tidy can be moved to the side.
Then remove the regulator from the hydrocorrector of the optics light, the tidy light switch knob, as well as the interior heater and fan regulators. To do this, pull the controls towards you.
After this, unscrew the two bolts securing the center panel trim on the sides; the trim itself can be moved towards you. Then you need to disconnect the connectors.
Now the key in the lock should be turned to position “0”, this will disable the anti-theft system. A connector with wires is connected to the lock itself; it must be disconnected. Next, unscrew the two nuts and two bolts, after which you can remove the steering column pipe with the switch.
Remove the choke handle located under the instrument panel. Pull it towards you so that you can feel the pull. You need to unscrew the two bolts that secure the damper guide rod, after which the choke can be removed.
Now you can unscrew four more screws that secure the heater control panel in the car. Unscrew the bolts located on the side of the shield on both sides. Also unscrew the lower console mounting bolts with nuts that secure the control panel lighting switch and the optics hydraulic corrector. To do this you will need a 22mm socket wrench, it must be high.
After completing these steps, you need to unscrew the bolt that secures the center console in the glove compartment. Then all you have to do is unscrew one bolt at a time on each side securing the center console. The console itself can then be dismantled.
As for installing a new high panel with tidy, this process does not present any particular difficulties. All dimensions at the mounting points on the body are the same, but this procedure also has its own characteristics. To install your new console, you will need the appropriate wiring harness. If you use an existing harness, then you will need to rearrange the terminals in it, taking into account the connection diagram. In addition, it will be necessary to change the cables leading to the heater to longer ones, the same applies to the speedometer cable. If you are installing a new console, you will also need other roof pillar side trims, these must be installed before you install the console. Since the new dashboard will not use a flow meter, the tube from it will need to be plugged. In addition, the signal to the tachometer will need to be supplied from wire K on the coil, which is connected to the speed sensor cable bracket.
Immediately before installation, you should reassemble the new console, and wrap the connection points of the blowers with electrical tape and, preferably, glue them with foam rubber or anti-creaking agent. It is also necessary to change the foam rubber of the heater, since the old one will no longer be able to perform its functions. Also make sure that the choke can close completely and remember that the cable from the new speedometer should be installed before you install the console. The assembly procedure begins with laying a new wiring harness and connecting all connectors. Before you finally assemble everything, turn on the dashboard and check how all the indicators and gauges work. After this, the console can be put back in place.

Pinout of on-board computer VAZ 2114

In standard drawings of electrical equipment, the BC block section is missing due to its uselessness. Initially, it is assumed that the motorist will not independently repair or maintain the complex control unit. But some users still take risks and install the system themselves. In older versions of cars, such a module is missing or insufficient for comfortable operation of the car in its modern form.

To connect wires to the module, you will need to buy a standard 9-pin header and connect the following wires to it:

1 – green wire comes from the fuel consumption sensor;
2 – the ignition cylinder is powered through an orange cable;
3 – power core from the battery, usually a red wire with a white stripe is supplied;
4 – grounding or ground, standard color – black;
5 – 6k line, usually a gray wire;
6 – Mute – green shell with a red line;
7 – the backlight in the standard pinout is output from the marker optics key;
8 – a sensor that displays the remaining fuel in the car’s gas tank can be connected directly.

How to prevent electrical equipment breakdowns?

In order for the VAZ 2114 pinout to be required as rarely as possible, the user is required to follow a number of simple rules and recommendations.

Periodically treat all metal parts with special oil. In this case, it is first necessary to clean the copper patches from oxides and traces of corrosion. Such lesions provoke a deterioration in the transmission of signals, which can be perceived by the car as a breakdown.
Every 20-30 thousand kilometers, check all equipment and plastic plugs for looseness or reduced fastening rigidity. With constant vibrations typical of vehicles, plastic clamps can fail and cause breakdown.
Monitor the correct battery charge and the serviceability of the generator. Some machine devices do not work correctly when there is a strong voltage drop.
Every 40,000 km, check the condition of the wires themselves. With constant use, the braids of the power cores may crack or dry out, which increases the likelihood of a short circuit in the on-board lines. This may also cause a fire.

How to connect and install

It is recommended to install and configure any musical device on the VAZ-2114 in accordance with generally accepted rules. Only in this case will the equipment work efficiently and perform all its functions.

Connection

To connect a radio to a VAZ-2114, just familiarize yourself with the procedure provided for any similar model (2115, 2109). The only difference will be in the location of one or another wire.

Connect the radio using this method:

Connect the musical equipment connector to the positive and negative poles of the power source (battery). In this case, the cigarette lighter plug can be used for switching.
Remove the cables from the speakers and connect them to the corresponding outputs on the device plug.
As soon as the wiring is connected, all potentially dangerous places are isolated using special tape. You can additionally protect the cable from accidental contact and the negative effects of moisture by using a corrugated tube.
An antenna is installed on the inside of the windshield or roof of the vehicle.
The cable running from it to the dashboard is laid under various parts of the car's interior trim.
The wire is connected to the radio directly or through an adapter.
