As I recall, the 2 black wires that come out of the middle together
should go both go to a crimped on ring terminal. The ring terminal is
screwed to the van sheet metal, behind the kitchen unit.  If so, one is
the ground for the led display panel and the other is the ground for the
fridge 12 volt element and fan. Is one of the black wires a larger
diameter than the other? I don't have time right now  to check this in
more depth. but maybe tomorrow.
