Re-wiring trailer harness.

So I have a 2013 tundra, and I am trying to get this trailer wiring harness set. Can anyone tell/show me what the 7wires on the two clips (5 and 2) run exactly? This way I can set them to the right places.

 

Not sure I fully understand what you are trying to do. Is the harness in the truck or are you trying to utilize it in your truck? Need more context.

That said, I can tell you the colors my 2012 Sequoia uses for the trailer 7 way. Much commonality between Sequoia and Tundra wiring.

Black - Power/Battery
Blue - Trailer brakes
Green - Right turn/brake light
Yellow - Left turn/brake light
Gray - Backup light
Brown - Tail light
White - Ground

Note, typically heavier gauge wire is used for Power, Ground and Brakes.

So, this is the harness for my truck, and I’m trying to hook up the 7pin. I think you have the right idea, and I’ll see if that works.
