Dave;

I retro-fitted that ABS switch myself. I wrote up a "how-to" on it - I'll
send you a copy separately to avoid flooding the list with a large PDF file.
It uses a couple of switches from a '89 - '91 200q (one for the switch and
the other for the ABS faceplate) and a relay. The actual "pulse to latch,
pulse to unlatch" relay required in the OEM system is hard to find unless
you have a pre-'93 to cannibalize, so I designed the retro-fit with readily
available parts.
Like you, I find it very handy under certain winter conditions. I decided I
really needed one after I "chattered" my way into an icy intersection with
the ABS hammering like mad and very little stopping going on.

Dan kindly hosted a bunch of my write-ups on www.s-cars.org, so it is
available there for download as well.

Hi All,

I was reading Fred Munro's seat heater switch LED replacement writeup at
www.UrS4.com, and noticed the ABS disable switch in his dash.  Has
anyone else installed this switch?

Any information on the part number for the switch (from Europe I'd think
since the ABS defeat switch was available there from what I understand)
would be appreciated.  As would any information about wether or not the
connector harness and wiring is present behind the switch panel on our
vehicles.  It would be great if this is a simple "upgrade".

I've found myself wishing for such a swtich several times a year on the
last few vehicles I've owned.  I'm out from the city a bit, and here in
Quebec tend to get deep snow several times a winter.  In deep snow it's
more effective to let the wheels lock up and "plow" the snow ahead
rather than using ABS.  Being able to disable the ABS in these
situations would be ideal.

Thanks!
-Dave
