I have a 2007 Chevy obs 3500 dually that I am trying to wire the tail lights on a custom bed I built. The wiring harness that feeds the tail light board and the trailer plug was damaged and I am not having any luck finding a diagram for this harness. I would like to purchase the three plugs for the lighting but so far I am finding the left and right lights and not the reverse plug. Any help would be greatly appreciated. LC

If this isn’t the correct one, perhaps you can find what you need on another page here:

Hope this helps

On the left side by the fuel fill is a camper harness you can use . Pretty straight forward. Green right turn
Yellow left turn
Brown marker/ tail
Light green lic plate
White ground
Red usual 12 v rv when connected up front.
Blue trailer brakes
Black reverse lights

Is there not enough of the factory harness left to plug in the rear lighting harnesses like these?
