* Under the hood in the fuse box: This is the most common location. The fuse box itself might be located near the battery or along the firewall. 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 models might have the fuel pump relay located within the fuse box inside the car, typically under the dashboard.
To find it definitively:
1. Consult your owner's manual: This is the best place to start. It will have a diagram showing the location of all relays and fuses.
2. Check online forums: Search for "1984 Ford Thunderbird fuel pump relay location" on forums dedicated to classic Ford vehicles. Owners often post photos and details about their specific models.
3. Use a wiring diagram: A wiring diagram for your specific year, engine, and trim level will show you the relay's location and circuit. You can find these online through various automotive parts websites or repair manuals.
Without knowing your specific Thunderbird's engine and trim level, providing a precise location is impossible. The above steps are the best way to find it.
