Towbar electrical connection:
1. Locate the car’s towbar connectors:
*They are usually located behind the rear bumper or under the rear seat.
2. Remove the connector covers:
*Use a screwdriver or Allen wrench to remove the mounting screws.
3. Connect the towbar connectors to the car connectors:
* Match the colors of the wires and connect them accordingly:
* Yellow – turn signal (right)
* Green – turn signal (left)
* Red – brake lights
* White – reverse
* Blue – fog light
* Black – earth
4. Insulate connections:
* Secure connections with electrical tape or heat shrink tubing.
5. Reinstall the plugs:
* Replace the connector covers and tighten the mounting screws.
6. Connect permanent plus (optional):
* If there is a permanent plus on the towbar, it must be connected to the car battery.
*Locate the wire on the tow bar, which is usually labeled “12V” or “+”.
*Connect it to the positive terminal of the battery.
7. Install the matching module (optional):
*If the vehicle is equipped with a CAN bus system, a conditioner may be required to resolve problems with malfunctioning or flickering tail lights.
*Follow the interface module manufacturer’s instructions for installation and connection.
8. Check the electrical operation:
* Connect the trailer to the tow bar.
*Turn on the turn signals, brake lights, and other functions on the trailer to make sure they are working properly.
*Use a multimeter to check the voltage at the trailer connectors to ensure proper connections.
Precautions:
* Before starting work, disconnect the negative cable from the car battery.
* Be careful when handling electricity.
* Do not connect the wires directly to the car chassis, as poor contact will cause problems.
*If you are not confident in your skills, it is better to contact a professional electrician.
