7 Pin Trailer Plug Wiring Schematic. There is a long thread on this forum that has all the part numbers, it is all about trailer hitches. The harness connector can be plugged into a seven-pin universal heavy-duty trailer connector available through your dealer.
Anyone know where to get and/or download a wiring diagram for the trailer light package. Not really a code issue I apologize, but can you provide a basic wiring schematic? If you get the wrong one, there's a permanent current drain.
Here is some information that I find useful when wiring trailer connectors, and the brake controller should be wired into the vehicles wiring according to the instructions that came with the brake controller and that identifies each wire from the brake.
Many people often have difficulties with the wiring of their trailer, and even after several attempts they still don't seem to get it right.
The blue wire is usually the electric brake wire that hooks up to your electric brake controller inside of the cab. You can also test the functions of each pin of the socket. This supplies power to the road lighting of your trailer or caravan.
