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.
