Factory Trailer Plug Wiring Diagram Anyone?

[ianjadkins]

Does anyone have a diagram of the plugs where the 7 prong wiring adapter plugs into the two factory plugs. I have a wiring issue and am not exactally sure if its my truck or trailer. Just need to know what the wires in the factory plugs are so I can make sure they go to the correct leads in the 7 wire plug.

Thanks,

Ian

Thanks for the help, I know the 7 wire trailer wiring, I just need to know what the factory wires are. My Truck Has two plugs that go into the seven wire trailer plug. I have a problem with the truck or trailer. I used a test light to find them, but I want to double check since I still have trouble with the trailer.
