Wiring Replacement 7-Way Connector on 2004 GMC Yukon Denali
Question:
My plug had broken off, leaving just the exposed ends. It is a factory 7 plug with tow package, would you have a wiring diagram to figure out which color wire is for what?

Expert Reply:
I was able to track down an online version of the owner's manual for your 2004 Yukon Denali and it listed the following wiring configuration for the factory 7-Way harness at the bumper:
Yellow: Left Stop/Turn Signal
Dark Green - Right Stop/Turn Signal
Brown: Tail/Running Lights
White: Ground
Light Green: Back-up Lamps
Red: 12V Power
Dark Blue: Trailer Brake
The Replacement 7-Way Trailer Connector # A10-7072VP that you referenced will work well as a replacement. I have attached a diagram that you might also find helpful as you connect the wiring from the truck (note the location of the functions not the colors on the diagram).
