1. Underhood Fuse Box: The majority of relays will be in the fuse box located under the hood. This box is usually near the battery and is often a large black plastic box. The relays are typically mounted inside, sometimes on removable panels or in slots. Consult your owner's manual or a wiring diagram for a specific map of the relays within this box.
2. Passenger Compartment Fuse Box (Sometimes): Some relays, especially those controlling interior functions, might be located in the fuse box inside the passenger compartment. This is usually found under the dash, often near the steering column. Again, your owner's manual or a wiring diagram will be your best guide.
To find the specific location of a *particular* relay:
* Consult your owner's manual: This is the first and best resource. It should have a diagram showing the fuse and relay box layouts.
* Use a wiring diagram: A wiring diagram for your specific year and model S-10 is invaluable. These are available online from various automotive parts websites or repair manuals (like Haynes or Chilton). The diagram will clearly show which relay controls what circuit.
* Look for markings: Relays themselves often have markings indicating their function (though this isn't always clear).
* Use a multimeter (advanced): If you're comfortable with basic electrical testing, you can use a multimeter to trace circuits and identify relays.
Caution: Always disconnect the negative battery terminal before working with electrical components in your vehicle to prevent shorts or damage.
