Ford F-150 (2021 – 2022) Fuse Box Location and Diagrams Guide
This guide provides information on the locations and diagrams of the fuse boxes for the Ford F-150 models from 2021 to 2022. Understand the methods for locating, identifying, and comprehending each fuse to facilitate effective maintenance and address common electrical problems efficiently.
IDENTIFYING FUSE TYPES
- A Micro 2.
- B Micro 3.
- C Maxi.
- D Mini.
- E M Case.
- F J Case.
- G J Case Low Profile.
- H Slotted M Case.
FUSE PRECAUTIONS
- 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.
- Always replace a fuse with one that has the specified amperage rating. Using a fuse with a higher amperage rating can cause severe wire damage and could start a fire.
