I think he meant for the video signal wire mostly. I intend to tap power/ground up there as well. Is that green wire an ACC positive or +12v constant? I'm guessing ACC since the homelink doesn't function with the X5 not in ACC. I'll have to find a constant up there (or run more wires) as I want bump detection on the camera.

Edit: NM Crowz, I'm sure this is a standalone unit with no signal wire to the headunit. I was thinking of one tied to the head unit like I am putting in.
