I am renovating a camper van. The van came with an Electrolux fridge connected to the gas bottle but with a tangle of disconnected wiring at the back.
Model number 114A2/
there is a terminal block with 2 black wires leading from it.
I assume there's no preference for which is live and which is Earth.
Any ideas before I ignite the neighbourhood?

Any direct current (DC) appliances need to have the correct polarity to work properly...don't connect anything up until you've discovered which is which! You'll need a multimeter to do this.
