I developed anxiety after reading about trailer lighting systems that are supposed to be connected to the car battery, and was extremely relieved to have installed these with doing that. The hardest part is installing the grounding screw. The instructions say to put it through a part of the sheet metal that's two layers deep, but I thought it only doable to poke a hole through one. I took the screw and hit it with a large hammer until it started a hole, and screwed it in manually from there.
