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?

I'd say most cars probably wouldn't have an ignition switched supply
readily available at the rear of the car. So unless provided by the car
maker for this job would have to be added. And hopefully done correctly.

Any car which offers an approved towbar will be equipped with a plug in
socket for the wiring loom for a caravan conforming to EU standards
(except it would seem from an earlier comment VW0
