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?

Check for lack of continuity between the pins.

Good point!

That should pick up the first level of bodging.

Should have mentioned that there are 3 different earths on the 13 pin
socket and each should go back to a vehicle earth and not be linked on
the socket.
