For your 2005 F-150, there are primarily three main fuse box locations you need to be aware of:

1. Passenger Compartment Fuse Panel: This fuse box is located inside the vehicle, typically under the dashboard on the driver’s side. It houses fuses for many of the interior and convenience features of your F-150.
2. Auxiliary Relay Box (with DRL): Some 2005 Ford F-150 models are equipped with Daytime Running Lights (DRL). If your truck has DRL, it will have an auxiliary relay box, usually found in the engine compartment.
3. Auxiliary Relay Box (without DRL): For 2005 F-150 models without Daytime Running Lights, there’s also an auxiliary relay box, located in the engine compartment, but with a slightly different configuration compared to the DRL version.
