Reverse light cable

[Tikki]

I have mounted a 7" multimedia stereo in my berlingo 08. Connected a camera to the reversing light back in the car. But i also need a cable from the reversing light connect it to the stereo to activate the camera menu on the stereo when i put the car in R.

So i hope i can acsess the cable in the front of the car. So i dont need to streach a cable from the rear to the front. There is a bundel of cables under the passenger Carpet. And any one know what colour the R-light cable has.

Colour varies , what you need to go by is the numbers on the cables.
Un fortunately I don't know what it is . Cant you check at the rear light cluster for the number, get the number and find if its in the loom you've found?
