* Under the hood in the fuse box: This is the most common location. The fuse box is typically located near the battery. Look for a box with numerous fuses and relays. The relay itself might be labeled, or you might need to consult your owner's manual or a wiring diagram to identify it.
* Inside the passenger compartment fuse box (less common): Some Bronco IIs might have the fuel pump relay located in a secondary fuse box inside the vehicle, often under the dash.
To find it definitively:
1. Consult your owner's manual: This is your best resource. The manual should have a diagram of the fuse and relay boxes showing the location of the fuel pump relay.
2. Use a wiring diagram: A wiring diagram specific to your Bronco II's year and engine will show you the relay's location and its connection points. You can often find these online through automotive repair sites (like Haynes or Chilton) or at an auto parts store.
3. Look for a relay that's likely the fuel pump relay: Even without a diagram, you can look for relays near other engine-related components within the fuse boxes. They're usually square or rectangular with multiple terminals. Tracing the wires leading to and from the relay might help you identify the correct one. Be careful not to touch live wires!
Remember to always disconnect the negative battery cable before working with any electrical components to prevent injury.
