Quick Answer
Your 2014 Ford F-150 is equipped with three fuse boxes to manage its electrical systems: the Power Distribution Box (PDB) located under the hood, the Smart Junction Box (SJB) located behind the passenger kick panel, and a smaller fuse panel in the rear of the truck, typically behind a removable panel in the cargo area or under the rear seat, depending on the cab configuration.
Power Distribution Box (Under Hood)
The Power Distribution Box is located in the engine compartment, near the battery. It contains high-current fuses and relays for major electrical components. Always verify the fuse panel lid diagram for your specific trim as variations may exist.

Relay Locations (SJB):
- R1: Accessory Delay Relay
- R2: Power Window Relay
- R3: Wiper Motor High/Low Relay
Rear Fuse Panel (Cargo Area / Under Rear Seat)
Some 2014 Ford F-150 models may have an additional fuse panel located in the rear of the vehicle, often behind a removable trim panel in the cargo area or under the rear seat. This panel typically protects circuits related to trailer wiring and rear accessories. Always verify the fuse panel lid diagram for your specific trim as variations may exist.
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| 1 | 30A | Green | Trailer Tow Battery Charge Relay |
| 2 | 20A | Yellow | Trailer Tow Park Lamp Relay |
| 3 | 20A | Yellow | Trailer Tow Left Stop/Turn Lamp Relay |
| 4 | 20A | Yellow | Trailer Tow Right Stop/Turn Lamp Relay |
| 5 | 15A | Blue | Rear 12V Power Outlet |

How to Test a Fuse
Testing a fuse is a simple process that can save you time and money. Here's how you can do it:
- Safety First: Ensure the ignition is off and the vehicle is in Park or Neutral with the parking brake engaged.
- Locate the Fuse: Refer to your fuse box diagram (usually under the fuse box lid or in your owner's manual) to find the fuse you suspect is blown.
- Visual Inspection: Many fuses have a small wire inside that
Before you pull a fuse on the 2014 Ford F-150
- Use the label printed on the panel cover or the owner's manual for your exact build. Layouts change with options, model year and build date, so a chart for another truck can be wrong.
- Replace a blown fuse only with the same amp rating. A larger fuse can let wiring overheat.
- A fuse that blows again right away means a short or failing component downstream. Find the cause before replacing it again.
- A good fuse doesn't prove the circuit works — relays, grounds and connectors fail too.
- Disconnect the battery before working near high-current fuses or cables.
