Dads 82 Speed control not working?

["Larry Noska" <lnoska@xxxxxxxxxxxx>]

My imperial seams to be missing a cable from the speed control servo.  The
FSM shows two cables, a cable from the transmission, and a cable to the
speedometer.  The one that goes to the speedometer is missing!!  Could this
provide data input to the brain for the speed control??  I haven't found the
cable in the FSM.  The wife has a dentist appointment today so won't be able
to get back to this puzzle until tomtrow???

Does any body know what it does?  The speedometer seams to be
working-without this cable!
