crystalworks is on a distinguished road
Ob, in the case where you want it powered all the time, just use a switched 12v on ignition to trigger a relay to power the camera. You will have to determine if your head unit switches to reverse automatically using the bus as crowz mentioned. If it does, great. The camera will be feeding it a picture all the time whether in reverse or not so your wiring would be done.

Edit: I see you are already on that course. Not sure what at the fuse box is pos 1 energized but some testing with a multimeter should determine that quickly enough.
