Ford Mustang fuse box diagrams: Complete & detailed schemes for all generations
The Ford Mustang’s electrical system has grown vastly more complex over six decades. A single blown fuse can disable headlights, power windows, the fuel pump, ABS, or even the starter. Below are the most complete fuse box diagrams available for every major generation, compiled from official Ford service data, owner manuals, LMR technical guides, Mustang7G forums, and verified sources like startmycar.com and mustangspecs.com.
Important notes for all generations:
- Always replace fuses with the exact amperage and type.
- Disconnect the battery before working on high-current fuses.
- Modern Mustangs (2015+) may require a scan tool after fuse replacement to clear codes.
- Diagrams can vary slightly by trim (V6/GT/EcoBoost/Dark Horse/GT500), transmission, convertible vs. coupe, and options. Always verify with your VIN-specific owner’s manual.
1st Generation (1964–1973) – Classic fuse panel
Location: Under the dash on the driver’s side, left of the steering column.
Many circuits use thermal circuit breakers (C.B.) or glass fuses (SFE/AGC/AGX). No under-hood box.
