Find fuse box and relay locations for the Ford E-350 and E-450 (2015-2019) with detailed diagrams. Ensure proper electrical system maintenance and reliability.
The Ford E-350 and E-450 (2015-2019) are part of the versatile E-Series lineup, known for their robust performance and adaptability. These vehicles are typically available as cutaway vans and chassis cabs, designed to serve a variety of commercial purposes such as shuttle buses, ambulances, and delivery vehicles. The spacious design and durable body styles make them ideal for customization, providing flexibility for specific business or utility needs.
The electrical systems in the E-350 and E-450 rely heavily on the fuse box and relays to control critical functions. The main fuse box is located inside the engine compartment, near the battery, and houses the fuses for essential systems like the lights, wipers, and ignition. A secondary fuse panel may also be found inside the cabin for additional components. Relays, positioned in the same areas, manage larger electrical loads such as the fuel pump, cooling fans, and starter motor. Proper inspection and maintenance of these components are essential for ensuring reliable performance.

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.

Ford E-350 / E-450 Year of production: 2015, 2016, 2017, 2018, 2019
Passenger Compartment Fuse Panel:
The fuse panel is located to the left of the brake pedal and mounted onto the lower left cowl panel. Remove the fuse panel cover to access the fuses.
If your vehicle is equipped with dual batteries, disconnecting the primary under-hood battery does not remove power from all circuits.
Power Distribution Box:
The power distribution box is in the engine compartment. It has high-current fuses that protect your vehicle’s main electrical systems from overloads. If the battery has been disconnected and reconnected, you need to reset some features. If your vehicle is equipped with dual batteries, disconnecting the primary under-hood battery does not remove power from all circuits.
