ford factory backup camera to avci f700bt

i've been working on this 01' f-350 super duty for about three weeks now and been searching all over for information on hooking up a factory backup camera... there was no 01 factory camera, he actually has an 08' tailgate with the 08' factory camera built into the handle. now, there are 5 wires coming from the camera so one can only assume the following: one is 12+ one is GND- one is a remote input from the backup lights and the 2 left over are the actual video wires pos and neg considering that the first 3 wires i mentioned are wrapped together in shielding, i can assume these 3 are the +- and remote but for some reason i cant seem to get the dang thing to work does anyone have a wiring diagram or any insight for me? i appreciate your help :)

i would say that those wires that are shielded are the signal wires. and why would it have 12v AND a remote? its a camera, it only needs to be on while the truck is in reverse. is one of the wires in the shielded bundle an UNshielded braided wire? did you test the wires with a meter to see what they really do?
