Testing Wiring on a 2007 Chevy Silverado to Install a Tailgate Light Bar
Question:
I need to know the color codes for the trailer wires on a 2007 Chevy Silverado LT. New body style. Trying to hardwire a tailgate light bar. Just need to know ground, running lights, left and right turn/brake. Thanks.

Expert Reply:
The 2007 Chevy Silverado should have trailer wiring already installed on it you could tap into but if there is no connector present you would just use # HM40975 and install it like in the video I have linked.
To determine the wire function on existing wiring you would use a circuit tester like # PTW2979. You can then probe each wire while someone runs through the various light functions to determine the wire functions. Testing is a must because manufacturers can use any color wire they want.
