Thank you both. In summary I need to transform C381 to C072 for the rear heated window. Only the white/green trace can be used, so I need to splice an earth, 12v feed and illuminator wire to make up the rest of the pins ?
Installed a new central console and double din unit using 300tdi loom.
bad new is that side lights and engine not starting now although can hear the relay switch clicking. Main beam and other electrics work and also, fuses and battery all look...
