What manual or schematic are you looking at. The Westy fridge relay is
controlled by the alternator. The red/black wire goes from one side of
the coil and grounds through the starter solenoid. The Blue wire goes
from the oter side of the coil and goes to the alternator warning light
circuit. The idea is that the relay is disabled during engine cranking,
(no ground) and the alternator has to actually be producing current to
operate the 12v heating element in the fridge. The contacts on the relay
are wired so that the fridge fan, water pump, and light panel are
connected with the battery on one side, and the fridge 12v heater
circuit is controlled by the relay.
In VWs the brown wire is almost always the ground.
Hope this helps.

Subject: Fridge wireing?

I am in the process of wireing in a westy fridge to my Syncro GL.
Question
on the 12V hook up. I'm looking at the manual and it appears the Black
is
Posative, Blue is Negative (-), and I don't know what the brown wire
does???
Any help is appreciated.

Randy
87' Syncro (Tiico)
