To be certain, you'll need to:
1. Consult a repair manual: A Haynes or Chilton manual specific to your 1996 Ford Explorer Sport will have diagrams showing the exact location of all components, including the EGR feedback control solenoid. This is the most reliable method.
2. Use a parts diagram: Online auto parts stores (like AutoZone, Advance Auto Parts, etc.) allow you to look up parts diagrams for your specific vehicle's year, make, model, and engine. Finding the EGR valve will usually lead you to the nearby solenoid.
3. Visual Inspection (with caution): With the engine cool, carefully inspect the intake manifold area near the EGR valve. Look for a small solenoid with electrical connectors. Be cautious around hot engine components.
Important Note: Before attempting any repairs or maintenance, always disconnect the negative battery terminal to prevent accidental shorts or damage.
