Learn about Ford F-150 2015-2017 fuse box and relay’s locations, functions, and maintenance tips for optimal vehicle electrical system.
The 2015-2017 Ford F-150 is a versatile full-size pickup truck available in several body styles, including Regular Cab, SuperCab, and SuperCrew, each catering to different needs for passenger space and cargo capacity. These models are also available in various trims, such as the XL, XLT, Lariat, King Ranch, Platinum, and Limited, allowing for a wide range of features and amenities. Key features include advanced infotainment systems, modern safety technology, and strong towing capabilities thanks to options like the 2.7L EcoBoost, 3.5L V6, and 5.0L V8 engines.
The F-150’s electrical system is essential for powering its extensive range of functions, including lighting, climate control, and infotainment. The fuse box and relay center, typically located under the hood and in the cabin, play a critical role in ensuring these systems work effectively. Fuses protect electrical components from overload, while relays help manage the flow of power to high-demand features like the headlights and starter motor.

WARNING
- Never replace a fuse with one that has a higher amperage rating.
- A fuse with a too-high amperage could damage the electrical part and cause a fire.
- On no account should fuses be repaired (e.g. patched up with tin foil or wire) as this may cause serious damage elsewhere in the electrical circuit or cause a fire.
- If a fuse blows repeatedly, do not keep replacing it. Instead, have the cause for the repeated short circuit or overload tracked and fixed.
- Terminal and harness assignments for individual connectors will vary depending on vehicle equipment level, model, and market.

Passenger Compartment Fuse Panel:
The fuse panel is in the right-hand side of the passenger footwell behind a trim panel.
To remove the trim panel, pull it toward you and swing it away from the side. To reinstall it, line up the tabs with the grooves on the panel, and then push it shut.
To remove the fuse panel cover, press in the tabs on both sides of the cover, and then pull it off.
To reinstall the fuse panel cover, place the top part of the cover on the fuse panel and push the bottom part until it latches. Gently pull on the cover to make sure it has latched properly.
Power Distribution 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.
