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.
