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. 62903
