Just installed a towbar which was really easy however the electrics are causing a problem.
I am using a 7 way relay kit and have managed to wire up the indicators however the brake and side lights are a problem.
I have identified two wires in the cars loom that activate the brake lights but the brake lights on the trailer stay on permanently.
What are the colours in the cars loom for the side lights and brake lights ?
How do you get around the issue that the trailer requires one wire for the sidelight and one for the brake light but on the car there only appears to be one wire for both?
