Neil,

I recently conducted a search of the archives with an eye toward writing
myself a how-to for moving the dome light, map light,mirror light,radio,
and the cigarette lighter off the main battery and onto the auxiliary
battery.  Numerous posts were distilled into the following, which I have
saved in my Vanagon files:(for a 1990, yours may be different)

Moving the Dome Light, Map Light, Mirror Light, Radio, Clock, and Cigarette
Lighter to the Auxiliary Battery

All of the above are powered by circuit #3 in the fuse panel. To remove
this circuit from the primary battery and connect it to the auxiliary
battery, do the following:

1.  Remove the fuse from circuit #3.  It will not be replaced.  To avoid
confusion in the future, you may wish to insert a dummy fuse (say a non-
working blown fuse) with a tag attached which references a note (perhaps a
copy of these instructions) placed in the owner�s manual or elsewhere,
which describes this change.

2.  Find the 2.5mm red wire leaving the back of the fuse panel that
connects with terminal 87 of the fridge relay under the driver�s seat.
Disconnect this wire at the fuse panel, install an in-line 15 amp fuse on
its end, then insert the other end of the fuse holder into the output side
(bottom) of circuit #3.  (this wire will now carry current from the
auxiliary battery under the driver�s seat, by way of terminal 87 on the
fridge relay, to circuit #3, whereas before this wire carried current from
the fuse panel to terminal 87 on the fridge relay)
Note: some may want the fuse close to the auxiliary battery, but my
preference is to have it more accessible just behind the main fuse panel,
rather than hard-to-get-to under the driver�s seat.

3.  Connect a new 2.5mm  red wire to the positive terminal of the auxiliary
battery, then connect the other end of this red wire to terminal 87 on the
fridge relay. These devices are now being supplied with current from the
auxiliary battery.

Note: 2.5mm wire = #10 awg
