Expert Reply:
While I don't have a wiring diagram for your vehicle, we do have some experience with wiring your vehicle. These are the color codes that GM typically uses and was verified on a 2007 Chevrolet Silverado with factory wiring.
Dark Green - Right Turn/Brake Lights
Yellow - Left Turn/Brake Lights
Brown - Tail Lights
White - Ground
Light Green - Backup Lights
Blue - Electric Brakes
Red/Black - 12 Volt Power
I recommend using a circuit tester, like part # PTW2993 if you do not have one, on your wires to make sure you have the right one for each function. Testing the wires should not take long, but you will want a helper to run through the light functions as you test each of the wires. If you're planning on replacing your socket to make your connections easier when towing, you can use the 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket # HM40975. This can be used with the wiring harness # PK11998 if needed.
