Hey there group, I'm trying to put a camper shell on my pickup to keep things out of the weather as I travel across Texas to gun shows. Does anyone know of a hot always on wire near the rear so I can tie in a light inside of the shell. Also, where's the easiest brake light lead to attach to for the top outside brake light on the camper. I've got a towing pkg on the truck, but don't have any type of wiring schematic. Any help would be greatly appreciated.
