I'm trying to get my van ready to pull a travel trailer and the only wiring harness i can find at the back of my van is this: can anyone tell me what this is?
If your trailer has sat for a length of time without being used, things may look alright on the outside to the naked eye. Not sure which wires attach to what on your trailer connectors? Offroaders Staff Editor Trailer & Towing.
