[ THIS MANUAL, YOUR KIT AND YOu-~
This Cruise Control Kit is a microprocessorbasedCruiseControl. It is designedfor easeof
installation andcanbeusedwith mostcars,light trucks andvans.Carefully follow the installation
proceduresin this manualfor bestresults.
DO NOT INSTALL THIS SYSTEM ON A DIESEL POWERED VEmCLE WmCH
HAS A MANUAL TRANSMISSION WITHOUT A DISENGAGEMENT
SWITCH (250-4206) ON THE CLUTCH PEDAL ASSEMBLY
Your vehiclemusthaveaVSS (Vehicle SpeedSensor)wire or anavailablesignalgeneratorfor
installation of this CruiseControl. Pleaseconsultvendor'sApplication Guide.
Low displacementengineswith limited vacuumwill get better performanceif avacuumreservoir
is installed.Vacuum reservoirs,pumps,regulatorsandother accessoriesareavailablefrom your
dealer,automotive servicecenteror most automotivepartsoutlets.
All through the instructionsthereareWARNINGS, CAUTIONS, AND NOTES that aremeant
to makeit easierfor you to put the CruiseControl onyour vehicleandsaferto use.We have
gatheredthesetips from peopleacrossthe country who havetold us about their problemsand
how they worked them out. Evenwith all thesereportsfrom the field, we cannotcover every
condition which you might encounter,therearejust too manydifferent vehicle makesandmodels.
We do our bestto tell you how to handlemostvehicles,but we mustDenendOn Your Good
Judgmentfor dealingwith the rest.
Therefore,we believeyou canunderstandwhy we strongly urge you to think carefully about
what could happento you, your passengersandyour vehicleif you useanytools, parts,fastening
methods,routing or procedureswhich arenot describedin this manual.
There is NO drain on the battery if the control switch is left on. The Cruise Control needs no
regular service.

1. Before Starting Installation:
Familiarize yourself with the Installation Instructions andCruise Control's components.
A. If vehicle is equipped with an ANTI- rnEFf RADIO. the radio c<xiemust be written down prior to
disconnecting battery cable. The c<xiemust be re-entered wbtJI the negative battery cable is reinstalled.
B. If vehicle is equipped with an AIR BAG. it is advisable to disconnect negative battery cable. However.
remember that some vehicles retain power to the air bag sysm when battery is diSCOOlleCted.
3. Removal of Negative Battery Cable:
Remove the negative battery cable before
installing the Cruise Control C(XDponents
as a safety precaution. (FilUre A) Battery

The Actuator Assembly must be programmed for the
vehicle on which it is installed. The TEN (10) programming
switches must be setaccording to the chart below in order
for the Cruise Control to operateproperly.
NOTE I: Both the Gray (VSS) and the Blue (TACH) wires
must be connected. (If vehicle VSS wire is not used.an
auxiliary road speedsource must beused.) SeeForm 12482
Yehicle Technical Information Guide (supplied in kit) for
VSS and TACH wire information.
NOTE 2: Ifosing an "OPEN CIRCUIT" control switch
with the Cruise Control, SwrrCH NUMBER 7 will have
to be OFF. On "OPEN CIRCUIT' switch, the ..ACCEL "

This section will cover the proper ways to usethe hardware available. Each section contains sample illustrations showing how
the coMector is usedin an actual installation. It must benoted however,that you should havean understanding of howeach
attachment method works sothat a proper installation is achieved.
There are six (6) different typesof throttle connections. ~

B. Pulley Assembly using T -Bar Adapter
C. Pedal Attachment

NOTE:
Whe. uliDg the Scad Chain Connector to connect
the Bead ChalD to the Cable Assembly you must
alwayl use the Bead ChaiD Cover. (Figure 7)
Failure to usethe Scad Chain Cover could possibly
causethe Scad ChalD or the Cable Assembly to hang
i. the Bead ChaiD Connector causing the throttle to
be held iD a partially OpeDposition. This coDditioD
cCMIldoccur wheD the Cruise Control is nOtbeing used.
A. Pu1lev Assemhlv Usinp the LOOP CABLE
I. On somevehicles it maybe necessaryto remove
the air cleaner sothe throttle pulley segmentis
showing.
2. Setthe pulley segmentin an OPEN throttle
JX)$ition.and removethe throttle cablefrom the
pulley.
3. Hold the Loop Cable betweenthe holes in each
sideof the pulley. Slide the barrel at the end of
the throttle cablethrough the slotted hole, then
through the Loop Cable and into the second
hole. (Figure 8)
..Connect the Loop Cable to the Cable Assembly
using the Bead Chai. Connector .
NOTE: Usethe Bead Chain Cover.
S.To 5«"Urethe Loop Cable to the throttle cable,

2. Attach the Bead Chain to the Two Bead
Connector. Securebeadsby folding down
the metal tabs.The following parts will be
usedwhen installed properly:
Two Bead Connector, Bead Chain,
Bead Chain Connector, and Bead
Chain Connector Cover. (Figure 16)
3. Removeclip or pin which retains throttle cable
(and washer ifprovided) and install Two Bead
Connector on the sameside of throttle cable as
the Cable Assembly will be anchored. This is
necessaryso that Cable Assembly and throttle
cablewill not cross.
4. The Two Bead may needto be bent sothat.it
clearsthe throttle cable. (Figure 17) Also, the
4" Tie Strap can be usedto hold the Two
Bead Connector to the sleeveof the throttle
cable. (Figurel7)

hole in bulkhead. A hole a couple of inches
to the left or slightly higher than the steering
column is usually a good place. (Figure 37)
NOTE: Check inside before drilling, sawing
or filing soyou don't damage anything.
4. From engine side, passfour pin connector
and VIOLET wire through hole. If you did
not hook up the BLUE TACH wire and
