Fog-lamp Switch Pinout?

["Matt Howe" <ismhowe@state.me.us>]

I'd like to start by saying how great this list server is, and more
importantly, how great the people are who use it.  I'm fairly new to the
quattro list, and I have asked several different questions, and nearly every
time I have recieved prompt answers from several different individuals
(which is especially cool since getting the answer from several places helps
to confirm it's accuracy) and I haven't (yet) even been flamed for asking
silly questions.  So, to all those who reply and provide useful information
to those of us who are less knowledgeable: Thanks, you rule!

BTW, I discovered why the Pentosin 7.1 hydraulic fluid is known as "green
gold".  First, it's green, and second it cost me $14 for a litre of the
stuff!  Green gold indeed!

Anyway, I have another question...  I'm planning to install some fog-lamps
and some additional driving lights on my '85 5ks, which apparently had
previously had some, since there is a stock-looking switch and some holes
under the bumper.  The question is:  On the factory fog-lamp switch, (which
is a 3-position switch) there are 5 pins with the following numbers: 75h
(narrow), 58a (wide), 31 (narrow), 86N (wide), 55S (wide).  Does anyone know
what these numbers correspond to, or how I could find out?  Thanks!
