The engine computer, PCM, is the voltage regulator.
On a 1993 Jeep Cherokee, the Powertrain Control Module (PCM) is typically located under the dashboard on the driver's side, mounted to the firewall. It can be accessed by removing the lower dash panel. Be cautious when handling the PCM, as it is sensitive electronic equipment.
The PCM is located on the firewall behind the coolant reservoir on the passenger side of the vehicle. Most notably are 3 large connectors.
In 1997 the Voltage regulator was integral part of the PCM. It is NOT a serviceable item

To change the PCM (Powertrain Control Module) on a Jeep Cherokee, first disconnect the negative battery terminal to ensure safety. Remove any necessary components obstructing access to the PCM, usually located near the engine bay. Unplug the wiring harness and unscrew the PCM from its mounting bracket, then replace it with the new unit and reconnect the wiring. Finally, reassemble any removed components, reconnect the battery, and ensure the new PCM is programmed or calibrated as needed.
