Factory Fog switch/Connections - Help!
I just recently installed a set of Hella XLs (and thanks to those who helped
me decide that these are a great set of lights... you were right!! They are
awesome!! I can't imagine driving without them now!! It is literally like
"night and day"!!)
After struggling a bit with the install on the front bumper (that's a bit of
a story, I'll spare the bandwith), they are finally up and running okay
(although a fine-tuning for aim is still in order). I have them wired right
now to the switch that came with the kit, but want to hook them up to a
factory fog light switch and place it appropriately in the dash with the
I thought that this would be a simple three wire hook-up (like the Hella
switch... ground, power, and supply), but was disappointed to see 5
pins/connectors on the back of the factory switch. Of course, since it is
supposed to fit in with an OEM wiring harness, it is not marked to show what
I need in order to hook it up. Naturally, so far, the dealer I bought it
from (Valley Motors here in MD... yes Mark, I agree with your caution about
them...) has been no help with looking up the wiring diagram for me.
So, I figured that I would consult with a far better resource that may
provide my answer in a quicker, more polite, professional manner... yeah,
the quattro list!!
With that said, can anyone tell me what the 5 pins represent on a factory
fog light switch (for a '92 100S... or are they all the same? Did they
change from prior models?) ? As I stated above, I need to know which is
ground, which one goes to power (+), and which one goes out to the relay.
On the back of the switch, the 5 pins are numbered. There are actually 6 pin
positions, but # 3 is empty/has no pin.
Here is a rough drawing of the back of the switch (I hope this lines up

Any help is appreciated. If no one knows what they represent, can anyone
tell me if they have done this, and how they hooked it up? Is there a way I
can determine all this with a multi-meter?
Thanks in advance.
