I looked for the same thing a few years back and couldn't fine
anything. I think that's because vwe didn't include any wiring for a
fog light switch.

What I ended up doing was increasing the headlight power by adding
relays like many on the list but added a 3rd relay for fog light. I
put the relays outside the van in a sealed electrical plastic box
behind the headlight then just ran one power wire to a small bus to
feed the relays. all the rest of the needed wires are already outside
the van as will be your fog light. You will need to add the extra
wire for the switch to the dash. I did that through the boot for the
radiator wires behind the driver side headlight.

Other idea on vans without AC is to use the spot for the 2nd speed
relay, I think it's 53 but I'm guessing you have AC?

With the onset of froggy weather and fog season I have had the
opportunity
to upgrade the frog er fog wiring.  Now the question is:  Is there
already a
front and rear foglight wiring in the wiring?  If so what color and
where
located.  I can't seem to find it in the 1989 wiring charts in the
Venerable
Vanagon Green Book.  Hints by pmail or by posting would be much
appreciated.

The plan is to upgrade by parking a new relay in the relay panel and
using
the existing wiring (if found) along with an added fuse to do the work.

Results will be posted.
