Troubleshooting Taillights for Trailer Wiring on 2012 Volkswagen Touareg
Question:
I have a t reg here with your harness and the left side turn and brake light are not working. Can you give me a detailed wiring diagram for the 4 pole and 7 pole to mate with this supplied harness. I have no signal out of the black box to the black with green tracer wire which is suppose to operate the trailer lights for the left side.

Expert Reply:
I have attached the installation instructions for # 118668 below. I do recommend using a Circuit Tester # PTW2991 for testing your connections. This will help ensure your ground connectors are working properly as well.
I do not see a black wire with green tracer coming out of the black box. The black wire is the 12V constant power. Your output wires are green for right turn/brake, yellow for left turn/brake, brown for running lights and white is ground.
I hope this will help you identify where the problem is occurring. It is also a good idea to check all the connections both on the wiring and vehicle to ensure none of the pins bent, broke or pushed out of their connector.
