A snow bank ripped the wire harness apart under the truck bed near the rear bumper including seven way towing harness, tail/brake/reverse lights. Do you have a diagram showing wire colors and what they do?

Hi and thanks for using 2CarPros.

I attached wiring schematics for all exterior lighting and towing provisions. I had to break the picture in two for it to fit.

The last two pictures are for the back up lights. Again, I had to cut it in two, but I overlapped everything so you can follow from one to the next.

Let me know if this helps of if you have other questions.

Take care,
Joe
