2012 F150 Fuse Diagrams
These diagrams show the fuse and relay locations, layout, a descriptions for a 2012 F150 Fuse
The 2012 F150 Fuse panel is located under the right-hand side of the instrument panel. To remove the trim panel for access to the fuse box, pull the panel toward you and swing it out away from the side and remove it. To reinstall it, line up the tabs with the grooves on the panel, then push it shut. To remove the fuse box cover, press in the tabs on both sides of the cover, then pull the cover off. To reinstall the fuse box cover, place the top part of the cover on the fuse panel, then push the bottom part of the cover until you hear it click shut. Gently pull on the cover to make sure it is seated properly.
