Thanks Again:) I've ordered a reverse camera, so will see how it turns out :) thanks again Darius :) great info there!

sorry for the late reply, working all weekend.
 
The camera is mounted int the back of the rear bumper bar insdie the bar itself and connected to the reverse lights. But since i can turn on the camera while driving forward, there must be a switch somewhere in the system.
See if i can draw a pic for you later.

sorry, completely forgot about this.
Put some scans up tommorow.

Sorry for late reply
the badly drawn cut is what i think it is mounted
Wireing on the other hand i'm not so sure. As a guess it would connect it to the existing reverse lights to turn on only when reversing however on my unit i can turn it on when driving.

i ended up mounting it above the numberplate and repurposing the light mount screw:
