Stan,
There's a page on my website with photos on
how-to install auxiliary lights (and where I installed relays).
http://www.geocities.com/harald_nancy/
I have Hella XL low beams on my vanagon.
The wiring diagram shows low-beam (or it's the same
for fog-light installation).
For driving lights, the wiring is basically the same,
except you hook up the switch to a high-beam lead
by the headlamp or somewhere in the dash by the fuse panel.
Driving lights have to be dimmed for oncoming traffic.
