In the OEM configuration, + power to the camper appliances/lights
should connect to the 30 buss. (B+) I have modified it since, but on
my older style ceramic fuse type fuse panel, that wire connected to
the "backside" (pre fuse) buss at a fuse. IIRC, the '85 could have
either the older or newer style fuse panel.

AFAIK, the Vanagon would not originally have a headlight relay; hi/low
beam is switched at the hi/low beam switch only.

It sounds to me like there is a battery isolator relay and the stock
fridge relay in the aux battery box under the driver seat.

I'm sure I'll be corrected by the experts if I'm wrong, but, if one
connects an extra + supply wire to an existing functioning circuit, it
is simply redundant. It's the loads on that circuit that  might
potentially overload the circuit.
