Where to Find Third Brake Light Circuit for Truck Camper Shell Third Brake Light
Question:
I want to hook up a topper dome light and tail and stop light to my standard 7 way GMC Sierra 1500 plug vehicle side. What do I need to hook up to do this? Also would like a wiring diagram on this. Thank You

The main trailer wiring harness is located under the truck bed, usually above the spare tire. There is usually a socket for your trailer connector to plug into, but if you peel back the wire loom you will find a light blue wire further up in the wiring harness that is intended for use for a third brake lamp on a camper shell.
I attached a couple pics to help you see where the wire is at.
