Hi all, My reversing camera has fallen/been ripped off. It was small, cubical and mounted to the left of the number plate lights to an approx 3cm square hole. It appears to have been wired with a small black cable with very thin white and red wires surrounded by fine wire shielding. Probably 6V. There are various reasonably priced reversing cameras on Trade Me but they come with their own phono plug/co-ax style cable as well as 12V power/earth leads, and I'd rather solder/connect at the rear door and not have to run cable through the car and take the screen out to connect up. Can anyone recommend a camera and help/point me to fitting/wiring instructions? Many thanks Bill
