2009 Ford F150 Power Distribution Box Diagram (Underhood)
The power distribution box, which houses high-current fuses, is situated in the engine compartment of your vehicle. These fuses play a crucial role in safeguarding the main electrical systems from overloads, ensuring their proper functioning. The high-current fuses within the power distribution box are coded using a specific system. This coding scheme helps identify and differentiate the various fuses.
Note: In the event that you need to disconnect and reconnect the battery, it's important to note that certain features may require resetting. This step is necessary to restore their functionality.
