To be certain, you should:
1. Consult your vehicle's repair manual: This will give you the most accurate location and diagrams.
2. Look closely around the intake manifold and throttle body: It's usually a small, cylindrical component with a single electrical connector. It might be mounted directly to the manifold, or on a bracket nearby.
3. Search online for a picture of a 1995 S10 engine bay: A quick image search specifying your engine size might show you the general location.
Remember to be cautious when working around the engine compartment. Disconnect the battery negative terminal before beginning any work to prevent accidental shorts.
