Where is the starter solenoid located on a 1994 Jeep Grand Cherokee V8?

On a 1994 Jeep Grand Cherokee V8, the starter solenoid is integrated into the starter motor itself. It's not a separate component like on some older vehicles. The starter motor is located on the engine block, towards the front, and usually on the passenger side (right side). You'll need to look closely at the starter motor; the solenoid is a part of its casing.
