Where is the starter solenoid for a 2002 ford ranger located at in engine compartment?

The starter solenoid on a 2002 Ford Ranger is typically mounted on the starter motor itself. The starter motor is located on the passenger side (right side) of the engine block, near the bell housing (where the engine connects to the transmission).

You won't see a separate, individual starter solenoid like on some older vehicles. Instead, it's an integrated part of the starter. To access it, you'll likely need to get fairly close to the starter, possibly needing to remove some components for better visibility and access.
