I just purchased your Kurt hitch and a wiring set up I need to know color code for Chevy Silverado 2004 25 HD trailer package not the kit that I bought from you. There is a light blue with a connector on it not sure what that goes to then there’s a dark blue I believe that goes to the brakes is it black or red in heavier gauge then light green dark green brown and yellow can you help please

I'm honestly not sure which factory wire colors carry which function on your Silverado. The best way to determine this is to actually test them for power using a circuit tester - you'll simply probe the wires in question while you activate each function in the cab (turn signals, running lights, etc) to see which wire carries power for each one. This will be the most accurate method for wiring up the truck.
