I used the stock GM back up light switch that mounts on the side of the 4L60E.
I pinned out the wires that made the reverse connection and ran it back to the rear. I then used 2- 2 way round LED lights and mounted them in the round bed holes on each side of the bed towards the top of the bed sides. When i apply the brakes these 2" LED's turn red. When I back up whey turn White.
I picked up the lights online on a big rig trucking website.
