Fuse box location

Passenger compartment fuse box

The fuse panel is in the right-hand side of the passenger footwell behind a trim panel and plastic key code cardThe location of the fuses in the passenger compartment: Ford Mustang (2015, 2016, 2017, 2018, 2019)

To remove the trim panel, lift it from the rear retaining hooks, while pulling it toward you and swinging it away from the side.
To reinstall it, line up the tabs with the grooves on the panel, drop the panel back into place, and then push it shut.
To reach the fuse panel, first remove the key code card.
Engine compartment fuse box

The power distribution box is located in the engine compartmentThe location of the fuses in the engine compartment: Ford Mustang (2015, 2016, 2017, 2018, 2019)
