Subject:      Aftermarket cruise control speed sensor
Content-Type: text/plain; charset="us-ascii"; format=flowed

I'm working on installing an aftermarket cruise control in my '86 w/
AT.  I've had this unit for years.  First it was on a 79 scirocco for a
couple of years, then on an 85 GTi for the 10 years I owned it.  Both of
those were manual transmission, so the unit just relied on the tach signal
to keep the rpms constant.  This won't work on the AT due to the slip in
the torque converter.  I actually have had some success using it, but only
up around 4100 rpms where I don't like to cruise.  Even so it sometimes
goes into surging and then disengages because it thinks something weird is
going on.  And it is right.

I still have the original manual for the unit.  It talks about a speed
sensor kit, but gives no details as to what exactly that contains.  The
unit was sold at my FLAPS under the Dana brand name, I guess I bought it in
the late 80's.  My question is what kind of signal is it looking for from
the speed sensor?

Thanks for any input.
