I was test wiring up my fridge and was wondering about that same thing.
I ended up running a positive lead to both the brown and the black and
ran a negative lead to the blue.  I think the black lead runs to the
actual refrigerator/heater/boiler and the brown one goes to a solenoid.
In any case it did work when I wired it up that way.

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.
