Ford Mustang Fuses and Relays. Ford Mustang Fuse Diagram.

In this article, we look at the sixth generation Ford Mustang, produced from 2015 to the present. Here you will find fuse block diagrams for the   2015, 2016, 2017, 2018, 2019, 2020, 2021, and 2022 Ford Mustangs   , get information about the location of the fuse panels inside the car, and also learn the purpose of each fuse.

Fuse Location Ford Mustang 2015-2022

The cigarette lighter (socket) fuses in the Ford Mustang   are fuses #53 (cigarette lighter) and #54 (auxiliary socket) in the engine compartment fuse block.

Fuse box location

Passenger lounge

The fuse panel is located on the right in the passenger footwell behind the trim panel and the plastic key code card.

To remove the trim panel, lift it from the rear retaining hooks by pulling it towards you and away from you at the same time.
To install, align the tabs with the grooves on the panel, rotate the panel back into place and close it.
To access the fuse panel, first remove the key code card.

Engine compartment

The junction box is located in the engine compartment.
