HELPFUL HINTS 1. BEFORE STARTING INSTALLATION: FAMILIARIZE YOURSELF WITH THE INSTALLATION INSTRUCTIONS AND CRUISE CONTROL COMPONENTS. 2. MATING CONNECTORS: A. WHEN DISCONNECTING CONNECTORS, HOLD CONNECTOR AND PRESS THE LOCK DOWNWARD WHILE PULLING CONNEC TORS APART. FIGURE 1 CAUTION: DO NOT PULL ON WIRES B. WHEN FIGURE 1 CONNECTING MATING CONNECTORS, PUSH CONNEC TORS TOGETHER UNTIL LOCKING MECHANISMS ARE FIRMLY LOCKED TOGETHER. FIGURE 2 3.
INSTALLATION STEP 1: WIRE HARNESS ROUTING LOCATION: DRIVER’S SIDE FIREWALL ACCESS. 1” VEHICLE MAIN WIRING HARNESS SLIT 1. ROUTE MODULE HARNESS THROUGH OEM MAIN WIRING HARNESS GROMMET, FIGURE 6, TO THE DRIVER’S SIDE COMPARTMENT. SECURE MODULE HARNESS WITH CABLE TIE TO MODULE BRACKET (ONCE INSTALLED). OUTSIDE THE VEHICLE, REMOVE 2. FROM OEM MAIN HAR- NESS GROMMET FROM BULKHEAD AT THE DRIVER’S SIDE. A 1” SLIT AT LOCATION SHOWN. CUT FIGURE 6 3. WHEN NESS. CUTTING SLIT, 4.
INSTALLATION STEP 4: THROTTLE ATTACHMENT LOOSEN THIS NUT ONLY LOCATION: ENGINE THROTTLE SHAFT AREA 1. LOOSEN “REAR” THROTTLE CABLE NUT ENOUGH TO CABLE BRACKET. RETIGHTEN THE “REAR” CABLE NUT. FIGURE 9 THE INSERT THE THROTTLE FIGURE 9 2. REMOVE THE PIVOT NUT FROM THE PULLEY SEGMENT OF THE THROTTLE BODY. LEVER BRACKET NUT. FIGURE 10 ATTACH AS SHOWN. THE THROTTLE REINSTALL THE OE 3. THREAD NUT BY HAND TO AVOID CROSS TIGHTEN 8MM NUT TO 60-72 IN LBS. DO NOT OVERTIGHTEN.
INSTALLATION STEP 6: BRAKE SWITCH CONNECTIONS LOCATION: BRAKE PEDAL ASSEMBLY HARDWARE: MATING CONNECTORS 1. DISCONNECT VEHICLE SWITCH. FIGURE 13 BRAKE SWITCH HARNESS FROM BRAKE 2. CONNECT MATING CONNECTORS OF CRUISE MAIN HARNESS ASSEMBLY TO THE VEHICLE BRAKE SWITCH AND HARNESS. FIGURE 13 3. ROUTE HARNESS ASSEMBLIES SO THAT THEY DO NOT INTERFERE WITH ANY MOVING COMPONENTS.
INSTALLATION STEP 8: POWER CONNECTION LOCATION: POWER, DRIVER SIDE CONNECTOR (1N) HARDWARE: : (1) FEMALE T-TAP CONNECTORS (RED) 1. LOCATE THE BLACK 11 2. ROUTE BROWN 3. INSTALL THE WIRE PIN CONNECTOR (POWER) RED T-TAP (1N) TOWARDS THE ON THE BACK SIDE OF THE (1N) 11 CONNECTOR ON THE (XA: PIN CONNECTOR. JUNCTION BLOCK, FIGURES 16A & 16B, FIGURE 16A GREEN, XB: BLACK/WHITE) PIN #6 WIRE AND CONNECT THE BROWN WIRE TO THE T-TAP 4. SECURE CONNECTOR.
INSTALLATION STEP 9: VEHICLE SPEED SIGNAL & NEUTRAL SAFETY LOCATION: PASSENGER 1. UNSNAP PLASTIC SIDE, LOCATED AT COMPUTER BENEATH PASSENGER DASH. COVER TO GAIN ACCESS TO THE 2. ROUTE LT GREEN (NSS) AND VEHICLE ECU LOACTED BENEATH THE PASSENGER SIDE GLOVEBOX. GRAY (VSS) WIRES FROM MAIN CRUISE HARNESS ALONG THE ECU HARNESS FIGURE 17, ECU LOCATED UNDERNEATH THE PASSENGER GLOVE BOX. FIGURES 17 & 18. BEHIND CENTER CONSOLE TOWARDS THE 3.
INSTALLATION STEP 10: CONTROL SWITCH LOCATION: LEFT SIDE LOWER STEERING COLUMN COVER 1. REMOVE LOWER FIGURE 21 LOWER STEERING COLUMN COVER 54MM (2-1/8”) STEERING COLUMN COVER. 16MM (5/8”) 2. USING THE LEVER WEDGE AS AN ANGLE TEMPLATE, DRILL 9.5MM HOLE IN LOWER SHROUD AS SHOWN IN FIGURE 21 FIGURE 21 3. ENSURE LEVER WEDGES ARE ASSEMBLED AS SHOWN IN FIGURE 22. TO PREVENT THE CRUISE CONTROL SWITCH DRILL 9.
INSTALLATION CONTROL SWITCH CONNECTION TO MODULE ASSEMBLY HARNESS 6. INSTALL 4 PIN CONNECTOR ON RED, BROWN, GREEN, AND YELLOW WIRES. INSTALL 2 PIN CONNECTOR ON TO BLUE AND BLACK WIRES OF SWITCH HARNESS. NOTE: THE MATING CONNECTOR TO THIS 4 PIN CONNECTOR WILL HAVE A RED WIRE MATING TO THE BROWN WIRE, ALL OTHER COLORS SHOULD MATCH. CONNECT 4-PIN AND 2-PIN CONNECTORS TO MODULE ASSEMBLY HARNESS. ENSURE THAT ALL PINS LOCK INTO CONNECTOR. FIGURE 24 7.

TROUBLESHOOTING A. ELECTRICAL TESTING: 1. TESTING OF THE CRUISE CONTROL SYSTEM IS BEST DONE AT THE (10) WIRES AT THE 2. DEPENDING UPON THE TEST BEING CONDUCTED, A VOLT OR OHM METER MUST A TEST LIGHT WILL NOT PROVIDE ACCURATE INFORMATION IN SOME CIRCUITS BEING CRUISE CONTROL MODULE. BE USED FOR ACCURATE RESULTS. TESTED WARNING: TEST LIGHTS MAY CAUSE DAMAGE TO THE VEHICLE. 3. USING A VOLT/OHM METER, CONDUCT THE FOLLOWING TESTS WHERE THE WIRING HARNESS ENTERS THE CRUISE CONTROL MODULE.
TROUBLESHOOTING B. ELECTRICAL TESTING DIAGNOSTIC: B-1....CHECK BRAKE LIGHT FUSE, BULBS, WIRES & CONNECTORS TO BRAKE SWITCH AND CLUTCH SWITCH IF MANUAL B-2.....CHECK IGNITION SWITCH LINK WIRES, CONNECTOR AND IGNITION FUSE. B-3.....CHECK IGNITION SWITCH LINK WIRES, CONNECTOR AND IGNITION FUSE, CRUISE SWITCH WIRES AND CONNECTOR. B-4.....CHECK CRUISE CONTROL SWITCH WIRES AND CONNECTOR. B-5.....CHECK VEHICLE ECU WIRE AND CONNECTOR, T-TAP AT VSS WIRE. B-6.....
