Here is a YouTube video you might want to watch. If your camper is pre wired there should be a black hooded piece of plastic on the back of the camper about a foot or two from the roof. That is where your wires come out. There is a plastic cover that comes out, your wires should be right there. I would also recommend a Furrion backup/observation camera and get one with the hood included. My camera did not fit the installed hood so I had to swap out the hoods. I would order it new on line from a reputable dealer to save a few dollars. It’s really not difficult to install if you’re at all handy. Also, Since my rear view mirror is useless pulling a camper I mounted the Furrion monitor to the mirror with some straps. Good luck and enjoy your camper.
