The 1999 Ford Mustang features two main fuse box locations critical for electrical systems. Knowing both ensures proper maintenance and troubleshooting.
Fuse Box Locations
Identify the fuse boxes based on standard placement in this model:
- Under-Hood Fuse Box: Located in the engine compartment, typically near the battery or adjacent to the windshield. Accessible after lifting the hood and removing a protective cover.
- Passenger Compartment Fuse Panel: Found under the dashboard on the driver's side, behind a small access panel. This secondary panel handles interior electronics.
Obtaining the Fuse Box Diagram
Secure an accurate diagram to reference fuses and relays:

- Consult the original owner's manual included with the vehicle for factory-specific diagrams.
- Obtain Ford factory service manuals through authorized dealerships or certified retailers.
- Access digital or print resources from reputable automotive publishers.
Tip: Match diagrams to your exact trim level for precise electrical specifications.
