At the risk of some duplication,I'm adding the following,for some
clarification and detail:
For any one needing to replace their OEM Cruise control, one choice is a
change to an electronic one similar to current autos. The Rostra, Ultra
II Cruise Control makes a very neat, compact and functional update to
modern standards. It is easy to move speed up or down by tapping the
control briefly or to return to a previous selected speed after a slow
down or stop.
The unit consists 1. of a 5"x4"x3" sealed electronic Actuator Control
(or Assembly)-P/N 250-1223
2.A small Pulse Generator, about 2" in dia. which monitors your speed
via the speedometer cable from the transmission- P/N 250-4153
3. A modern appearing hand control mounted on the end of the original
turn signal arm after cutting off the plastic end. P/N 250-3032
Instructions are included and Duanne adds some supplemental ones for the
GMC.,however the following will give GMC'ers an idea of proceedures.
1. All old cruise control components are removed,including transducer,
brackets, vacuum hosing and off switch at brake pedal. This frees up
some room at the rear of the motor around the distributor and makes for
a cleaner and neater appearing motor.
2. Short speedo. cable from trans. is curved left of motor well and
screwed into pulse generator. The longer cable is scewed into the other
side of Pulse Gen. and routed in an easy arc up to the speedometer.
3.The Actuator is mounted on a bracket in the engine area to one of the
bolts for the drivers seat base.
4. A small cable from Actuator is routed beside the accelerator cable &
hooked to the same spot as the chain for the OEM cruise control
5. End of the turn signal is cut off and a new control is slid on and
held in place with two small allen screws.Mount it so lever can be seen
from driving position.
6. Electronically via wiring harness unit is connected to + power behind
glove box and at brake pedal and grounded along the aluminum frame of
the motor well.
To locate dealers one can go to web site ,however,
I purchased mine through Duane Simmons, and he and Richard have more
info on Genes site.
Another number was given on the Net for one of the components however to
my knowledge it is the same unit, however different distributors may
have a different number. It would be wise to double check this.
