Where is the relay for fuel pump on a 1990 bronco II?

The fuel pump relay location on a 1990 Ford Bronco II is under the hood in the Power Distribution Box (PDB). However, the PDB is sometimes referred to as the fuse box or relay center. It's typically located near the battery.

Unfortunately, there isn't a single definitive diagram available online to pinpoint the exact location *within* the PDB for every 1990 Bronco II. The relay may be labeled, but it could also be unmarked. You'll need to:

1. Locate the Power Distribution Box: Look near the battery, often on the fender well or firewall.

2. Consult your Bronco II's owner's manual: It should have a diagram of the fuse and relay box showing the location of the fuel pump relay. This is your best resource.

3. Visually inspect the relays: Some relays might be labeled. You might also find a wiring diagram sticker inside the PDB lid.

4. Use a wiring diagram: A wiring diagram specific to your Bronco II's year and engine will show the relay's location and circuit. You can often find these online through forums dedicated to Ford Broncos or at auto parts stores.

Important Note: Always disconnect the negative battery cable before working with electrical components to prevent shorts and injury.
