Truck is a 2001 2500hd with a 360. Only had the truck for about a month. This is the first time I tried towing with it, I have trailer brakes but no lights at all. Brake, running, turn signals, nothing. I've checked fuses and trailer relay, all working properly.
This is making me think I have a wiring problem somewhere. Does anyone know what color wires control what going to the 7 pin plug?
