That’s the circuit I am using. Wire is strung from that connector for th3rd brake light into the area behind the tail light. I just need to know how to get it up and through the box to the interior of the pickup bed?
Just getting around to running wires from underneath the car up to inside ARE topper. I have wires up inside the tail light housing. Just need to know how to get them to the inside of the bed so I can then connect to wires from 3rd brake/dome light.
is there a access hole or do I have to drill one? Thanks
