Yeah, the computer varies idle speed and other thing depending on
vehicle speed.
The speed sensor is pretty simple, its just a mechanical switch driven
by a cam that turned by the speedometer gear. There should be eight
pulses per revolution. If you pull one out and hook a meter up to it you
should see eight breaks in continuity as it turns a full revolution. If
you don't see this, then its broken internally. From there it's a
matter of check for these same pulses up the wiring harness to the input
pin on the logic module.
There is more information on speed sensors and logic module pinouts on
http://minimopar.net along with an article about upgrading to a newer
style unit that is not mechanical is liable to last longer.
Good luck,
Stefan

My speedo is not working either. I did hook up the the sensor, but the
speedo didn't work. Last time I rode in the car, before it was mine,
the speedo worked fine. I used the same transmission and wiring that
was in it previously. I did notice that the wiring for the speed /
distance sensor was spliced. In the box of spare parts I acquired with
the car I also noticed a different style plug pigtail that had the same
two colored wires as the speed distance sensor plug that was spliced
onto the harness. I didn't question the splice at first, as the wiring
colors on the plug and the harness matched, but I am starting to think
that it could have been wired incorrectly, especially after seeing a
different looking connector pigtail that was cut off of the harness.
Which harness does the speed / distance sensor connect to?
Right now, it is wired into the same harness that the reverse light
switch, and the transmission ground is wired. That connects to the main
harness by the battery in an 8 position (2 rows of 4) white colored
connector. Is this correct? I was unaware that problem could be related
to an idle problem which is why I never mentioned it in my last email.
Is there anyway to pinpoint if the wiring or the speed sensor is bad
aside of buying another sensor and trying that?

Either you forgot to hook up the speed/distance sensor or there's a
bad connection there. If your speedo is working, then your sensor is
good.
