Just a quick question.
With modern 13 pin connectors there is a pin for providing power to a caravan fridge. Pin 10, ignition controlled.
As far as I can tell this is not supported by the standard wiring in German cars until ver recently.
Is there any obvious way (apart from tracing the wiring) to prove that this is a separate power supply and not just bodged from the existing pins?
Cheers
