2009 Ford F450 Fuse Box Diagram (Power Distribution Box)

The power distribution box in the engine compartment is a crucial feature of the 2009 Ford F450. It acts as a protective enclosure for high-current fuses, effectively shielding the primary electrical systems of your vehicle from potential overloads. This ensures the safety and proper functioning of your vehicle’s electrical components.


To access the power distribution box and replace fuses in your F450 truck, you’ll need to follow these steps:

  1. From inside the vehicle, locate and pull the hood release handle positioned beneath the lower left corner of the instrument panel.
  2. Proceed to the front of the vehicle and release the auxiliary latch positioned below the passenger side of the grille, adjacent to the headlamp. Slide the handle to release the auxiliary latch.
  3. Lift the hood upward until the lift cylinders secure it in an open position.

For precise instructions on disconnecting and reconnecting the battery, it is highly advisable to consult the Maintenance chapter in the Owner’s Manual. This chapter provides detailed guidelines on the correct procedures for battery replacement.
