I determined I need a new PCM for my 1997 Jeep Grand Cherokee Laredo, 6-cyl, 4 speed auto trans.
Bought a PCM (programmed for my vehicle and mileage) disconnected the battery and installed reconnected battery. Everything great except guages don't work, i.e., tach, speedometer, oil pressure, water pressure.
Help please.
