To find it, you'll need to:
1. Consult your owner's manual: This is the best resource as it will show a diagram specific to your engine.
2. Look near the oil filter: The sending unit is usually close to the oil filter and relatively easy to access. It's a small electrical component with one or more wires connected.
3. Refer to a repair manual specific to your Ranger's engine: A Haynes or Chilton manual will have detailed diagrams and instructions.
4. Search online for images: A Google Image search for "1992 Ford Ranger [your engine size] oil pressure sending unit" might show pictures of the location on similar engines.
Remember to disconnect the negative battery cable before working on any electrical components to prevent accidental shorts.
