To use the Prodigy P3 # 90195 on your 2007 Chevy Silverado 2500 you will need to connect the wiring that is already present under your dash just above your left shin as you sit in the driver's seat. The wire colors are (1) Red/Black wire, (1) White wire, (1) Light Blue/White wire and (1) Dark Blue wire, and possibly (1) Orange wire.

You will connect the wires like this: (GM to Brake Controller Pigtail)

Red/Black to Black (Battery Power)
White to White (Ground)
Light Blue/White to Red (Brake Light Signal)
Drk Blue to blue (brake control output)
The Orange will not get connected. It is the Center High Mount Stop Lamp

I've attached an article with more information on under hood connections and have also attached a video to assist.
