To find it, you'll need to do the following:
1. Consult your owner's manual: This is the best starting point. The manual should have a diagram showing the location of all fuses and relays.
2. Check the underhood fuse/relay box: This box is typically located near the battery. The cover should have a diagram showing the location of each relay. Look for a relay labeled "Fuel Pump" or that has a diagram suggesting a fuel pump symbol (often a gas pump image).
3. Check the interior fuse box: This is usually located under the dashboard, often near the steering column or on the driver's side. Again, look for a relay labeled "Fuel Pump" or with a corresponding symbol.
4. If you can't find it visually, use a wiring diagram: A wiring diagram specific to your 1996 Ford Bronco 5.8L will show the relay's location and its circuit. You can find these diagrams online through auto parts websites or repair manuals (like Haynes or Chilton). You'll need to look for the diagram related to the fuel pump circuit.
Important Note: Before attempting any work on electrical components, always disconnect the negative (-) terminal of the battery to prevent accidental shorts.
