Are you a 2006 Ford F150 owner and are in search of its fuse box diagram and location? Don’t fret; this guide has it all covered for you. I will provide all the essential details necessary to find and understand its contents so you can tackle electrical issues or make necessary changes with confidence.
Knowing these locations is crucial when troubleshooting and making modifications. In this guide, I have shared information regarding the importance of the fuse box, how to locate the fuse panel inside the car, and what assignment each fuse holds.
Why Is the Fuse Box a Significant Part of Your Vehicle?
Before diving deeper into the details of your 2006 Ford F150’s fuse box, it’s essential to understand its function within its electrical system.
A fuse box serves to protect all circuits within your car from overloads or short circuits, which could potentially cause damage or fires; each circuit connected has a fuse that breaks when excess current passes through it.
Fuse blowouts provide essential protection from further electrical current flowing to a circuit, thus limiting potential damage or hazards. They ensure that minor problems, like short-circuiting in your radio, don’t escalate into larger ones that threaten the safety and functionality of your vehicle.
Where Is the Fuse Box Located In Your Vehicle?
Identifying the location of the 2006 Ford F150 fuse box is equally essential to understanding its function and diagram. The Ford F150 2006 model has two types of fuse boxes that are located in two separate locations:
Passenger Compartment Fuse Box/ Power Distribution Box
The fuse panel can be found under the right-hand side of the instrument panel behind its cover and contains all fuses used in passenger safety for the Ford F150 (2004-2008).

Auxiliary Relay Box
The relay box can be found inside the engine compartment on the left fender of your vehicle – typically located inside a black plastic box with an easily removable lid.
