Administrators Moses Ludel Posted September 14, 2016 Administrators Share Posted September 14, 2016 Hi, Mario...The aftermarket HEI distributor in your engine should have a tach lead. This tach signal is designed for G.M. gauges or aftermarket tachometers. I'm not sure whether this signal will work with your stock ZJ Grand Cherokee's tachometer. You need to research the voltage required at the ZJ tachometer and compare this with the output voltage signal from the HEI aftermarket distributor. It may be easier to install an aftermarket tachometer that will work with the HEI distributor. The speedometer on a ZJ is driven from the transfer case. If you use the stock ZJ transfer case, the existing speedometer drive and sensor are at the transfer case. The drive and sensor will continue to work just as they do with the 42RE transmission. If you use the transfer case from the XJ Cherokee AX15 donor vehicle, it is most likely an NP231 that also has a speedometer drive unit. Early model speedometer drives are for cable driven speedometers, the later Jeep speedometers are electronic. The donor NP231 transfer case should have a drive gear and sensor at the transfer case. No cable involved, just wires. If you use the NP231 drive and sensor, make sure the sensor uses the same wire count as your ZJ. To simplify this, try to use the ZJ sensor and drive unit from the ZJ transfer case if it will fit properly. This will match with the wiring and your ZJ speedometer.
