I am installing my Hella spare battery kit and the diagram is a little
confusing with current wiring in my 81 Westy
I have the two wires coming from the drivers seat powering the
sink/stove/fridge cabinet. One is power and the other is relay to keep the
fridge from running on 12v when the ignition is off. So when I put in my 2nd
battery and a terminal block the new Hella relay will do the same (I assume
from the diagram) as the relay wire under the seat.

Do I just ignore the vehicles relay wire under the seat and use the one in
the new relay then wire the new aux battery to the terminal block and run
the power wire for the fridge cabinet to this fuse block ???

Some thing sticks out here as "wrong"... it seems to me that the original
relay wire should be connected but where ???
