Wait, unless you are talking about camshaft.. LOL I saw cam and just assumed camera.. Which did you mean? I was re-reading your post on my page and was like... wait.. is he talking about the camshaft? lol If so, then no, my knowledge is mostly in electronics
Not specifically with cameras, but I do have experience wiring stuff up to the battery so I could help you get the wires to where they need to be without damaging anything or exposing them. When you get it, your welcome to hit me up and I can give it my best shot with advice, I am sure between me, you and the manual we could figure it out.
That sounds like a pretty cool idea, do you already have a screen or are you buying one of the backup cams from autozone that already have like a 3 inch screen?
