So buying a new camper that has pre-wired for Furion camera. The camera comes with another 5" screen you are supposed to mount in the truck. I would like to see if I can get it to show on the 12" screen instead. I'm assuming i will need to use a different camera but more interested in what I will need to add to my truck. My truck currently only has the tailgate camera. I don't have any plugs on the bumper like some do. I also do not have the fancy mirror. What parts would I all need to make this work?
