Ford Mustang (2015 – 2022) Fuse Box Diagrams & Location User Guide

This Ford Mustang (2015–2022) fuse box diagram and location guide is extensive. Find each fuse, understand its purpose, and replace defective ones to keep your Mustang’s electrical components working properly and safe.

Fuse Box Locations

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 card.

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.
After replacing a fuse, return the key code card to the original position. To reinstall the trim panel, lineup the tabs with the grooves on the panel, drop the panel back into place, and then push it shut to reinstall the trim panel.

Engine Compartment Fuse Box
The power distribution box is located in the engine compartment. It has high-current fuses that protect your vehicle’s main electrical systems from overloads.

WARNINGS
Always disconnect the battery before servicing high current fuses.
To reduce risk of electrical shock, always replace the cover to the power distribution box before reconnecting the battery or refilling fluid reservoirs.
