85 westy -- I put an optima yellowtop under the bench seat on the far
left (when facing front).   Left the charging relay under the driver's
seat and ran additional 8 gauge wire from there to the bench seat
location.  I didn't know about the #12 red wire / fusebox trick, so I
ran extra wires under the carpet to the radio, cigarette lighter, and
to the fluorescent light to move them onto the Aux battery circuit.


Pros:

* it fits very snugly next to the heater box

* a short wire run from there to an extra fuse box in the "secret"
compartment, where the rest of he westy wiring/fuses are.  There's a
convenient ground spot in the bench seat area as well (seatbelt
mounting point).

* Mounted a 300W inverter on the front of the bench seat, also a short
wire run.

* Side benefit:  I left the carrying handle on the optima and use
heavy-duty spring clips with rubber sheaths.  As a result, in a bout
30 seconds I can remove the aux battery entirely for jump starts or
camp lighting.   Not easily done if the battery is under the driver's
seat.

* no modification of the battery is required, and an even larger
battery would fit.  under-driver-seat location are often tight.

Cons:

* takes up valuable bench seat space

* the 85s have chronic aux battery charging problems due to the long /
thin wire run from alternator to starting battery.  The location under
the bench seat makes this worse.  I plan to solve this by running a
beefier parallel wire from alternator to starting battery.   I could
also run a wire directly from alternator, through the body to the
bench seat, though this sounds like more work.

* if you have a messy under bench seat, beware of metal object
shorting out your aux battery!
