Hi gent does anybody know where on one of these I can find this on a connector under the dash, I know there is probably one off the alt but it's buried.

It's for the relay on the towbar fridge circuit that should only come on when the circuit is charging.

It is a normal relay and not a smartcom version.

Cheers
