+Travis Crawford With screws... Ok just kidding. We ran the cabling from the front firewall under the truck to the bottom of the front of the bed... under the tool box. We drilled a 3/8" hole in the bed and the bottom of the tool box. We used rubber grommets at the penetrations, and simple wire loom for appearance. We attached the cabling to the inside of the bed and the inside of the toolbox so that the wiring would be out of the way and invisible. I used 18/4 cabling for this one. then split it in the toolbox per side, effectively making it 18/2 to the lightheads.
