Ford F150 Fuse Box Diagram: Year and Location 1997-2026
The Ford F150 fuse box diagram changes by model year, so the first step is matching your truck to the correct electrical layout. A fuse number that powers the fuel pump, radio, blower motor, or power outlet on one F-150 can control something completely different on another year.
Most F-150s use at least an interior fuse panel and an under hood power distribution box. Newer trucks also route many circuits through the Body Control Module, while certain configurations add equipment-specific circuits.
Use the generation guide below to identify the right panel first. For any fuse not specifically listed here, verify the exact model-year Owner’s Manual before replacing it.

How to Find the Correct F150 Fuse Diagram by Year
Ford redesigned the F-150 electrical system several times between 1997 and 2026. Even within one generation, fuse numbers and protected circuits can change.
| Model Years | F-150 Generation | Main Fuse Layout |
|---|---|---|
| 1997 to 2003 | 10th Generation | Interior panel plus power distribution box |
| 2004 to 2008 | 11th Generation | Passenger-side panel plus high-current distribution box |
| 2009 to 2014 | 12th Generation | Passenger panel plus engine compartment box |
| 2015 to 2020 | 13th Generation | Passenger footwell panel plus engine compartment box |
| 2021 to 2026 | 14th Generation | Body Control Module fuse box plus under hood box |
Ford’s own manuals demonstrate why you should not assume one generation uses identical fuse assignments throughout. The 2014 and 2015 F-150s, for example, use substantially different fuse numbering for several major circuits.
Before checking a fuse, confirm the model year, fuse box, fuse number, amperage, and protected component.
Where Are the Ford F150 Fuse Boxes Located
Most F-150 electrical systems divide protection between low-current cabin circuits and higher-current under hood systems.
Passenger Compartment Fuse Panel
On many newer F-150s, the interior panel sits on the right side of the passenger footwell behind a trim panel.
Ford places the 2020 passenger compartment fuse panel in this location. Access requires pulling the trim panel toward you, then removing the fuse-panel cover.

The 2010 F-150 also places its passenger fuse panel under the right side of the instrument panel.
Older 1997 to 2003 trucks use a different location. The panel is below and to the left of the steering wheel near the brake pedal on commonly documented 10th-generation layouts.
Engine Compartment Fuse Box
The under hood power distribution box handles higher-current systems such as the starter, fuel pump, blower motor, trailer equipment, PCM power, cooling fans, and major control-module feeds.
Ford identifies the 2014 power distribution box in the engine compartment and warns owners to disconnect the battery before servicing high-current fuses.
Auxiliary Relay Box
Some F-150 configurations use additional relay hardware.
The 2014 SVT Raptor, for example, has an auxiliary relay box near the left-hand rear corner of the engine compartment. It contains relays for the auxiliary switches and front camera washer.
Recommended Best Deal Products
Do not use a Raptor relay layout for a standard XL, XLT, Lariat, King Ranch, Platinum, or other configuration unless Ford documentation shows the same circuit.
2021 to 2026 Ford F150 Fuse Box Diagram
The 14th-generation F-150 has a more complex electrical architecture because the lineup includes conventional gas engines, hybrid PowerBoost models, additional driver-assistance hardware, USB charging systems, trailer electronics, and other equipment.
Ford’s 2021 manual separates the under hood fuse box from the Body Control Module fuse box.
A useful 2021 under hood reference includes:
| Fuse | Rating | Protected Component |
|---|---|---|
| 4 | 30A | Fuel pump |
| 11 | 30A | Starter motor |
| 13 | 40A | Blower motor |
| 15 | 25A | Horn |
| 55 | 30A | Trailer tow park lamps |
| 56 | 20A | Trailer tow stop and turn lamps |
| 58 | 10A | Trailer tow backup lamps |
| 69 | 30A | Left-hand windshield wiper |
| 100 | 15A | Left-hand headlamp |
| 101 | 15A | Right-hand headlamp |
| 107 | 30A | Trailer tow battery charge |
| 125 | 10A | USB smart charger |
| 139 | 5A | USB smart charger |
These assignments come directly from Ford’s 2021 F-150 documentation. Some entries vary between gas, diesel, and hybrid configurations.
Why 2021 to 2026 Fuse Numbers Need Exact Year Verification
Do not extend the 2021 table blindly through 2026.
Ford’s current 2026 fuse data starts the under hood box with 30A Body Control Module feeds at positions 1 through 3, followed by other high-current circuits. Its interior panel also uses its own numbered layout, including dedicated circuits for equipment such as the wireless charger and power window controls.
That confirms the rule for current trucks: use your exact model-year diagram.
2015 to 2020 Ford F150 Fuse Box Diagram
The 2015 redesign changed the fuse architecture substantially from the 2009 to 2014 generation.
The passenger compartment fuse box sits on the right side of the passenger footwell behind trim. Ford’s 2015 documentation lists circuits such as demand lighting, memory modules, door-lock motors, trailer brake control, audio, and electronic modules in this panel.
The under hood box handles larger circuits.
For the 2015 model year, Ford lists these useful examples:
| Fuse | Rating | Protected Component |
|---|---|---|
| 22 | 30A | Windshield wiper motor |
| 34 | 25A | Trailer tow park lamps |
| 35 | 20A | Trailer tow stop and turn circuit |
| 43 | 25A | Horn |
| 49 | 30A | Trailer brake control module |
| 56 | 20A | Fuel pump |
| 59 | 30A | Starter |
| 60 | 40A | Blower motor |
Ford also identifies separate relays for the fuel pump, starter, PCM, windshield wipers, blower motor, and electric fans.
What Changed by 2020
The 2020 passenger panel still sits in the right-hand passenger footwell, but its assignments should not be copied directly from 2015.
For example, Ford lists 2020 passenger-panel fuse 2 as a 7.5A circuit serving memory-related functions, while fuse 3 is a 20A driver-door-lock circuit.
This is why the physical fuse-box shape alone cannot confirm the correct fuse number.
2009 to 2014 Ford F150 Fuse Box Diagram
The 12th-generation F-150 also uses a passenger compartment panel and an engine compartment power distribution box.
On the 2010 F-150, Ford locates the passenger fuse panel under the right side of the instrument panel. The manual provides a numbered diagram with fuse positions extending through the upper 40s.
Some verified 2010 passenger-panel examples include:
| Fuse | Rating | Protected Component |
|---|---|---|
| 1 | 30A | Moonroof |
| 5 | 10A | Keypad illumination and related SJB circuits |
| 6 | 20A | Turn signals and stop lamps |
| 7 | 10A | Left low-beam headlamp |
| 8 | 10A | Right low-beam headlamp |
By 2014, the power distribution box includes a much larger group of high-current fuses and relays. Ford identifies relays 1 through 7 for PCM, starter, blower motor, rear defrost, electric fan, trailer park lamps, and run/start functions.
Useful 2014 examples include:
| Fuse or Relay | Rating | Protected Component |
|---|---|---|
| Relay 2 | Relay | Starter |
| Relay 3 | Relay | Blower motor |
| Relay 8 | Relay | Fuel pump |
| 17 | 30A | Trailer brake control |
| 22 | 20A | Instrument-panel auxiliary power point |
| 27 | 20A | Fuel-pump relay power |
| 65 | 20A | Instrument-panel auxiliary power point |
| 66 | 20A | Center-console auxiliary power point |
| 72 | 20A | Rear auxiliary power point |
The 2014 passenger panel separately uses fuse 29 at 20A for the radio and fuse 22 at 20A for the horn.
If you are diagnosing a 2013 no-start condition, a failed fuse is only one possibility. Truck Guider’s guide to the 2013 Ford F150 fuel pump reset switch location covers the related fuel shutoff system.
2004 to 2008 Ford F150 Fuse Box Diagram
The 11th-generation F-150 uses another distinct fuse and relay layout.
Ford’s 2008 Owner’s Guide places the fuse panel under the right side of the instrument panel.
Some useful 2008 references include:
| Fuse | Rating | Protected Component |
|---|---|---|
| F09 | 20A | Fuel pump relay and fuel injectors |
| F101 | 30A | Starter solenoid |
| F105 | 30A | Electric trailer brakes |
| F110 | 20A | Cigar lighter and diagnostic connector |
| F113 | 30A | Wipers and washer pump |
| F116 | 30A | Blower motor |
| F117 | 20A | Instrument-panel power point |
| F118 | 30A | Heated seats |
The same Ford guide lists R06 as the blower-motor relay and R303 as the fuel-pump relay.
The 2008 truck also has a separate fuel-pump shutoff switch in the front passenger footwell behind the kick-panel access cover, positioned to the left of the fuse box.
1997 to 2003 Ford F150 Fuse Box Diagram
The 10th-generation trucks are electrically different from later F-150s.
These trucks commonly use a passenger compartment fuse panel below and to the left of the steering wheel plus a separate power distribution box under the hood.
For the 2003 F-150 specifically, documented examples include:
| Fuse | Rating | Protected Component |
|---|---|---|
| Interior 1 | 15A | Audio |
| Interior 3 | 20A | Cigar lighter and data-link connector |
| Interior 11 | 30A | Windshield wiper system |
| Interior 16 | 20A | High-beam headlamps |
| Under hood 1 | 20A | Power point |
| Under hood 7 | 20A | Horn |
| Under hood 10 | 20A | Fuel pump |
| Under hood 13 | 15A | Air-conditioning clutch |
The 2003 data above is a legacy fuse reference rather than Ford’s current online manual interface, so owners should compare it against the fuse label or original Owner’s Guide supplied with the truck.
Which F150 Fuse Controls Common Electrical Problems
The quickest way to diagnose an electrical failure is to start with the failed component, then match it to your model year.
| Problem | Verified Example | Fuse or Circuit |
|---|---|---|
| Dead fuel pump | 2021 | Under hood fuse 4, 30A |
| Dead fuel pump | 2015 | Under hood fuse 56, 20A |
| Dead fuel pump | 2008 | Fuse F09, 20A and fuel-pump relay circuit |
| Dead fuel pump | 2003 | Under hood fuse 10, 20A |
| Blower does not run | 2021 | Under hood fuse 13, 40A |
| Blower does not run | 2015 | Under hood fuse 60, 40A |
| Blower does not run | 2008 | Fuse F116, 30A |
| No cigar lighter power | 2008 | Fuse F110, 20A |
| No cigar lighter power | 2003 | Interior fuse 3, 20A |
| Trailer brake problem | 2014 | Fuse 17, 30A |
| USB charger dead | 2021 | Fuse 125 or 139 depending on circuit |
These examples prove why searches such as “F150 fuel pump fuse” need a year attached. Ford changed both position and amperage across generations.
If the blower fuse checks good but the HVAC system still does not work, the problem may be elsewhere in the climate-control circuit. See our Ford F150 air conditioning troubleshooting guide before replacing unrelated electrical parts.
How to Check and Replace an F150 Fuse in 4 Steps
A fuse protects the wiring and electrical component from excessive current. Replacing it with a larger fuse defeats that protection.
Find the Correct Fuse
Match your model year to the correct interior or under hood diagram.
Do not choose a fuse based only on position or color. Confirm the circuit description and amperage.
Switch the Truck Off
Turn the ignition off and switch off electrical accessories.
For high-current fuses in the power distribution box, Ford instructs owners to disconnect the battery before service.
Inspect the Fuse Element
Remove the fuse with the proper fuse puller and inspect the internal metal element.
A visibly broken element normally indicates an open fuse. A multimeter or fuse tester gives a more reliable confirmation when the break is difficult to see.
Install the Same Amp Rating
Replace the failed fuse with the same amperage rating specified by Ford.
Never install a higher-rated fuse because the replacement keeps blowing. That can allow the wiring to carry more current than the circuit was designed to handle.
Why Does the Same Ford F150 Fuse Keep Blowing
A fuse that blows again shortly after replacement usually indicates an unresolved electrical fault.
Common causes include shorted wiring, damaged insulation, water intrusion, an internally failed component, overloaded accessory wiring, damaged trailer wiring, or incorrectly installed aftermarket equipment.
If a fuel-pump circuit keeps failing, also confirm that the problem is not being confused with another part of the fuel shutoff system. On applicable trucks, our 2013 Ford F150 inertia switch location guide explains the separate safety-shutoff component.
Do not keep installing replacement fuses until the circuit stays powered. Repeated fuse failure is a reason to test the circuit for excessive current or a short to ground.
Which Ford F150 Fuse Diagram Should You Use
The correct Ford F150 fuse box diagram is the one that matches your exact model year and equipment.
Start by finding the correct panel, then verify the fuse number, amperage, and protected circuit. Pay extra attention to PowerBoost, diesel, Raptor, trailer-tow, heated-seat, auxiliary-switch, and other equipment-specific circuits.
Ford’s own documentation warns that online Owner’s Manual information can vary slightly from the manual originally supplied with a specific truck. The original manual remains the primary reference for that vehicle.
If the fuse tests good, stop replacing parts at random and diagnose the rest of the affected circuit.
Ford F150 Fuse Box Diagram FAQs
Does the Ford F150 Have More Than One Fuse Box
Yes. Most F-150 model years have an interior fuse panel and a separate under hood power distribution box.
Certain versions also add auxiliary relay boxes or equipment-specific electrical protection. The exact arrangement depends on year and configuration.
Where Is the Fuse Box on a Ford F150
On many 2004 and newer F-150s, the interior fuse panel is on the passenger side under or behind the instrument panel trim. Ford places the 2020 panel in the right-hand passenger footwell.
The 1997 to 2003 layout instead places the interior panel near the driver’s side lower dash.
What Fuse Controls the Cigarette Lighter on a Ford F150
There is no single F-150 cigarette-lighter fuse number for every year.
On the 2008 F-150, Ford identifies F110 as a 20A cigar-lighter and diagnostic-connector circuit. A documented 2003 layout uses interior fuse 3 at 20A for the cigar lighter and data-link connector.
Where Is the Fuel Pump Fuse on a Ford F150
The location changes by year. The 2021 F-150 uses under hood fuse 4 at 30A for the fuel pump, while the 2015 truck uses fuse 56 at 20A.
Check the exact-year diagram before pulling either fuse.
Which Fuse Controls the Radio on a Ford F150
The radio circuit changes across generations and newer trucks may divide audio, display, SYNC, amplifier, and infotainment power across several circuits.
For example, the 2014 passenger panel lists fuse 29 at 20A for the radio, while other audio-related circuits use separate fuse positions.
Can I Put a Higher Amp Fuse in My F150
No. Replace a failed fuse with the rating specified for that circuit.
A higher-amperage fuse can allow excess current through the wiring instead of opening the circuit when a fault occurs.
Why Does My F150 Fuse Keep Blowing
Repeated fuse failure usually means the protected circuit still has an electrical problem.
Check for damaged wiring, shorts, overloaded accessories, failed components, trailer wiring faults, moisture, or incorrect aftermarket connections before installing another fuse.
