I was going though a Cherokee at my local junkyard and saw this yellow box little research later, I found this to be the cruise control module. So I look up to see everything I need and found a website that has the factory manual on the cruise control system. Link to it http://jeep-manual.ru/index.php?page=78 Also Haynes manual for Cherokee/Comanche/Wagoneer on 12-31 has the electrical diagram for the cruise control List of items you will need: Cruise Control Module Control Servo Speedometer Cables Upper and Lower. Upper cable is picture below Speed sensor Turn signal/ windshield wiper stalk with cruise control switch Wire harness Clutch Switch not necessary but is nice if you have manual transmission Vaccum Valve/Brake Switch i believe Vaccum hardline on the servo to the vacuum reservoir Vacuum reservoir (football shape) Finding Parts Most of the parts are behind/under the dash near the gauges and steering column. The Servo is in the engine bay on the passenger side near the closed coolant bottle. Speedometer lower cable is near the output of your transmission/transfer case.

I’ve been trying to add cruise control to my 89 MJ 4.0 5-speed with parts pulled from junkyard XJ’s. I believe I have everything and have tried a bit of troubleshooting but can’t get it to work. Any help or insight would be much appreciated. Here’s the install list: • cruise control wire harness • cc harness plugged to “ACC” in fuse box on truck with inline 4 amp fuse unbroken • speedo cable switched to two piece with speed sensor • speed sensor plugged to cc harness • brake switch swapped out for the one with extra terminals - plugged to cc harness • brake sensor (aka vacuum dump valve) & bracket mounted and properly adjusted on brake pedal with the sensor plugged into connector from stock wiring harness and big vac line going to servo • servo mounted with cable connected to throttle body and connected to both cc harness plug and stock wiring harness plug • yellow cc module plugged into cc harness • cruise equipped turn signal lever installed and plugged into cc harness • football-shaped vacuum reservoir in place of the ball one with small vac line running to servo Here’s all I’ve done in terms of troubleshooting: • I have multiples of the module, speed sensor, servo, and harness and have tried various combinations excluding the harness because I know it needs a repair. • I have checked the resistance of the turn signal lever as instructed in the FSM and it seemed to all check out so I think no wires are broken in it. • Small vac line at servo sticks to my finger when pulled off servo so it has vacuum but I’m not certain it’s enough. Any recommendations on a vacuum measuring device? All AC conrtrols work and reservoir seems to hold vacuum. • I have also plugged off the large vac line at the servo to eliminate the brake dump valve if it was the leaky culprit Also, if any one has a spare sensor and bracket for the clutch petal on a manual transmission I’d love to buy one.

I'm looking for the cruise control servo that gets mounted to the passenger fender. I'll also need the cable and fender mount. Anyone have this?

Background: 91 Eliminator - cruise control would lock on and keep accelerating. I had to turn the engine off, coast to the side of the interstate and disconnect the cable at the throttle body. Picked up a "new" actuator (the vacuum motor with the cable to the throttle body) at P&P and finally got around to starting the replacement today. As I was removing the actuator I noticed a lot of slack in the vacuum line going diwn behind the bumper to the vacuum ball. I managed to move things around enough to see that there is no vacuum ball, just a screw in the rnd of the line. My question - Could the absence of the vacuum ball (reservoir) cause the cruise to lock on and keep accelerating? Or, is it's absence just coincidental (which is what I'm thinking)? I plan to replace the vacuum ball in either case, but need to know if it causes/contributes to the problem.
