Ford F-350 (2000 – 2003) Fuse Box Location & Diagrams
The Ford F-350 (2000–2003) features multiple fuse boxes that control essential electrical systems. This user guide provides clear diagrams and locations, helping owners quickly locate, inspect, and replace fuses for hassle-free maintenance and repairs.
Fuse Box Locations
Passenger Compartment
The fuse panel is located below and to the left of the steering wheel by the brake pedal. Remove the panel cover to access the fuses.
- To remove the fuse panel cover, turn the panel fasteners counterclockwise.
- To remove a fuse use the fuse puller tool provided on the fuse panel cover.
Engine Compartment
The power distribution box, trailer tow and electronic shift on the fly relay blocks are located in the engine compartment near the brake master cylinder. The power distribution box contains high-current fuses that protect your vehicle’s main electrical systems from overloads.
Always disconnect the battery before servicing high current fuses.
Always replace the cover to the Power Distribution Box before reconnecting the battery or refilling fluid reservoirs.
