The master cut-off is a small item but important. A premium quality switch like this heavy duty Flaming River piece gives trouble free service.

The mounting and control is trick. It is bolted through the bed wall into the area behind the taillight. The lever connects to a control rod that exits through the back-up portion of the taillight lens.

Then a Morse cable will also connect to a lever inside the truck so power switch can be operated by driver. The second photo is looking back toward the taillight mounting area.

More photos of this soon.
