Hi

i fitted a reverse sensor kit on my Doblo a while ago. To find out which the reverse light wire was i used a 12v test lamp. Just turn the ignition on but don't start it, then pop it in reverse. Test each wire at the multiplug until the test lamp lights up.

There's a few different methods of of how to connect the wires up. You can use scotch locks, which is the easiest & most basic way of doing it. Or you can actually cut the reverse light wire & use an inline crimp connector.

The best way is just to bare a 10-15mm length of the wire & solder the reverse sensor unit power feed wire to it & then use some heat shrink to seal it up.

The reverse kit is a doddle to fit

IF you dont wanna go messing with the wiring looms

have a look for the reverse sensor on the gearbox

You might find its a standard 2pin waterproof connector - cheap off ebay
You could quiet easily join into the wiring (an adaptor+extension) so to speak and in via the cabin to the sensor box at the back
