[A4] B5 Switch Locations

[Doug Johnson]

My '99 q has two switches to the left of the hazard light switch, the front 
fog light switch and the rear fog light switch, but the right-hand position 
to the left of the hazard light switch is vacant.

What switch is typically located in that position, and is it possible for 
the average ham-fist to get wiring to that location?  <idea in mind...>

Thanks!
