I bought a Keystone Cougar (17) with a sticker saying 'Backup Camera Prep'. I think some trailers have the camera housing already attached. Mine does not. I assume there is a power cable somewhere near the top running light. So if I going to start drilling holes in the trailer skin where should I do it. I don't any info from Keystone on this. I really don't want to poke holes unless I know exactly where to do it. Can anyone help on this?
