Ford E-350 (2002 – 2008) Fuse Box Location and Diagrams
Diagrams and locations of Ford E-350 fuse boxes from 2002 to 2008 are covered in this blog. Learn about each fuse, its function, and how to quickly identify the right fuse to solve electrical problems.
Fuse Box Locations
Passenger compartment fuse panel
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 a fuse use the fuse puller tool provided on the fuse panel cover.
Power distribution box
The power distribution box is located in the engine compartment. The power distribution box contains high-current fuses that protect your vehicle’s main electrical systems from overloads.
Always replace the cover to the power distribution box before reconnecting the battery or refilling fluid reservoirs
Relay modules
- Instrument panel relay module
The instrument panel relay module is located behind the radio in the center of the instrument panel. - Engine compartment relay module
The engine compartment relay module is located in one of two places depending on which type of engine your vehicle is equipped with:- Gasoline engine: driver side of the engine compartment above the brake master cylinder.
- Diesel engine: passenger side of the engine compartment behind the power distribution box.
