Wiring diagram of the trailer device 7 contacts

Attachment of the trailer of the car is carried out on a towbar - the trailer ball device. It connects to the wiring of the car, allowing the driver to include dimensions, fog lights and turn signals on the trailer. The electricity is connected using a special socket - it has 7 or 13 contacts. Regardless, uses the wiring diagram of the trailer 7 contacts or 13, you may need a smart connection, which reconciles the electricity of the vehicle and the trailer on it.

some subtleties

On simple cars like VAZ 2107 connection of the socket of a towbar to the car is connected by wires to regular conducting, which is responsible for the rear optics.

Standard electricity connection is based on the principle of "dad-mom", does not present any difficulties, as the connectors are sold in all car shops. To make soldering the connector easy and consistent, showing the power scheme, wires vary in color. It is better to choose copper stranded wires to connect the wiring.

Thermostats of the towbar socket 7 pin is the most popular today. However, electrical outlets for European cars may differ from similar devices for passenger cars of domestic production in the location of signal wires.

The question arises: how to connect the socket in this case? A similar problem arises in that case, when the fork on the car has 13 contacts, and the towbar connector - 7.

To connect electricity, when it comes to different connectors, a special smart connection is used. It allows you to connect contacts in cases, when unsoldering does not match.

When choosing an outlet, you should pay attention to the presence of a rubber seal on the back for waterproofing contacts

The scheme of connection of the socket of a towbar on 13 contacts looks like this, that the wires on it are arranged in this way:

  • 1 - left turn;
  • 2 - fog lights;
  • 3 - land;
  • 4 - right turn;
  • 5 - right size;
  • 6 - stop signal;
  • 7 - left dimension;
  • 8 - reverse;
  • 9 - long load current;
  • 10 - power;
  • 11 - free;
  • 12 - free;
  • 13 - land.
