Finding Circuit for Third Brake Light and Dome Light for Camper Shell Installed on 2015 Silverado
Question:
I have a 2015 chevy silverado Z71 with towing package. What do I need to do or buy that would help me easily wire a 3rd brake light on a camper and the dome light?

Expert Reply:
Typically near the 7-way wiring on Chevy trucks there is a dedicated third brake light circuit that is to be used for wiring up the third brake light of a camper shell.
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.
The trailer wiring that runs to the 12 volt accessory circuit of the 7-way in the 1:00 position could be used to power a dome light in the camper as well.
