What are the Correct Wiring Connections Between the Trailer and the Tow Vehicle

Question:

I need a diagram of how the plug is wired to make sure that it is wired the same as my tow vehicle. I am specifically concerned to match up the heavier gauge wires for power, ground and brakes. Thanks

I have attached a wiring diagram that will show the typical arrangement of the towing wiring on your vehicle and the corresponding wires on the trailer side.

The basic wiring identification is as follows:

Green - Tail & Running Light
Black - 12V Power
Brown - Right Turn and Stop
Blue - Brake Control Output
White - Ground
Red - Left Turn and Stop
Yellow - Reverse Lights

I also attached an article on trailer wiring that can give you more info for you to review.
