2006 Ford F450 Passenger Compartment Fuse Panel Diagram
You can find the passenger compartment fuse panel in your 2006 F450 easily. It’s located below and to the left of the steering wheel, near the brake pedal.
To get to the fuses, you’ll need to take off the panel cover. It’s a simple process.
Just use the finger slots on top of the panel and pull it downward. As you do that, the top clips of the panel will come loose, and the panel will come off smoothly.
