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

A TT ACHING CABLE ASSEMBL y TO THROTTLE
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. ~
A. Pulley Assembly using Loop Cable
B. Pulley Assembly using T -Bar Adapter
C. Pedal Attachment
D. Ford Throttle

FIGURE 7
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,
punch a small hole in the Bead Chain Cover
and slide the ." Tie Strap through the hole and
-' -.we to the existing throttle cable. (Figure 9)
