I seldom post on this list as I have minimal mechanical skills and therefore
have little to contribute, but have benefited greatly from this list.  I
want to put an auxiliary battery in my '85 Westy GL.  I have read a lot
about it in the archives, but have not been able to find blow by blow
instructions of how to simply put in the relay that you can purchase from
Bus Depot.  I don't need to put in a charger or inverter.  I have e-mailed
the Bus Depot who responded very quickly (thanks BD!) with the wiring
diagram that they send out with this relay.  Since I am not very mechanical
I took it to my VW guy, who by his own admission has only put in a few of
these, and he had some questions about this diagram and installing auxiliary
batteries this way in general.  His questions were as follows:

1.      Is there a particular point on the fuse panel to connect to (i.e. a
certain terminal with a letter or a number)?
2.      Is there an auxiliary fuse box?  If not, how to isolate and power
those components that you want?
3.      Wouldn't heavier gauge wire, by 1 or 2, be better than what is
supplied?

So I am hoping that someone can give me blow by blow instructions of how to
install this thing to give to my mechanic and also answer his questions.  I
am hoping to be able to power my lights, stereo, and possible some 12v
stuff.  If my questions seem really simple and dumb I thank you for your
patience.

Thanks,
