Materials:
*Trailer plug and socket (usually 7 or 13 pins)
* Wiring of suitable size (for example, 10-15 AWG)
* Wiring terminals
* Electrical tape or heat shrink tubing
* Multimeter (for checking wiring)
Directions:
1. Preparing the car:
* Find a suitable location to install the trailer socket.
* Route the wiring from the trailer socket to the appropriate terminals on the tail lights, turn signals and brake lights.
2. Preparation of the trailer:
* Install the trailer plug onto the trailer.
* Route the wiring from the trailer click to the corresponding terminals on the tail lights, turn signals and brake lights.
3. Connecting contacts:
*Match the terminals on the trailer socket with the terminals on the trailer plug according to the following diagram:
| Contact | Function |
|—|—|
| 1 | Left turn signal |
| 2 | Right turn signal |
| 3 | Earth (mass) |
| 4 | Left side light |
| 5 | Right side light |
| 6 | Brake lights |
| 7 | Earth (mass) |
| 8 | Reverse (optional) |
| 9 | 12V DC (optional) |
| 10 | Not used |
| 11 | Left fog light (optional) |
| 12 | Right fog light (optional) |
| 13 | Electric brake (optional) |
4. Termination of wiring:
* Connect the wiring using terminals.
* Insulate connections with electrical tape or heat shrink tubing.
5. Check:
* Check all connections with a multimeter to ensure proper continuity.
* Connect the trailer to the vehicle and check the operation of all lights, turn signals and brake lights.
Note:
*Connection type may vary depending on the type of trailer plug and socket used. Always check the instructions for your specific equipment.
* It is important to use properly sized wiring as excessive current may cause overheating and damage to the wiring.
* Always use safety precautions when working with electricity.
