My '81 calif. westy didn't come with a stock aux. battery relay, but I
managed to pull one from a newer westy.  Can anyone tell me what the wiring
scheme is?  I assume that I need to connect ground, auxiliary positive,
main battery positive, fridge/light wire, and a few other wires (possibly
one from the dash alternator light and 'ignition on')??  Thanks much for
the help!
