If you own a Ford E450 van, you know it takes a lot of responsibility to keep it running smoothly. One crucial tool is the fuse box diagram, which contains information about your vehicle’s fuses and their respective locations. In this article, we will explore everything you need to know about the Ford E450 van fuse box diagram, including its layout, functions, and troubleshooting tips.
What is a Fuse Box Diagram?
A fuse box diagram is a graphic representation of your vehicle’s fuse layout. It provides a detailed guide showing which fuses are responsible for which electrical systems in your car. The diagram also gives you information regarding the amperage and rating of each fuse, as well as their exact location in the fuse panel.
Having a fuse box diagram is essential because it can help you identify electrical issues quickly. It can also save you the hassle of guessing which fuse is responsible for a malfunctioning system. If your Ford E450 van’s fuse box diagram is missing or illegible, then you’re in the right place.
Ford E450 Van Fuse Box Diagram Layout
The Ford E450 van has two fuse boxes, one located on the driver’s side of the dashboard, and the other under the hood. Let’s go over the details of each one.
Under the Hood Fuse Box
The under the hood fuse box is located on the driver’s side of the engine compartment. It contains 20 fuses and six relays, which control various electrical systems in your Ford E450 van.
| Fuse Number | Amperage Rating | Function |
|---|---|---|
| F1.1 | 30A | Trailer electric brake controller |
| F1.2 | 20A | Horn relay |
| F1.3 | 15A | PCM (Gasoline only), Mass Air Flow Sensor, Electronic Throttle Control, Fuel Pump (Diesel only) |
| F1.4 | 20A | PCM power relay |
| F1.5 | 15A | Speed Control Servo, Brake Switch, Clutch Switch, PCM (Diesel only) |
The table above shows some of the fuses and their functions in the under the hood fuse box. For the complete layout, including the relays, please refer to your vehicle’s owner’s manual.
Driver’s Side Fuse Box
The driver’s side fuse box is located behind the kick panel on the left side of the dashboard. It contains only six fuses, which control critical systems like the airbag module, power door locks, power windows, and instrument cluster.
| Fuse Number | Amperage Rating | Function |
|---|---|---|
| F2.1 | 10A | Instrument Cluster, Odometer |
| F2.2 | 10A | Air Bag Module |

How to Troubleshoot a Blown Fuse
If your Ford E450 van is experiencing electrical issues, a blown fuse may be the culprit. Here are some steps to follow when troubleshooting a blown fuse:
Step 1: Check the Obvious
The first step when you suspect a blown fuse is to check the obvious. Look at the fuse box diagram to identify the fuse that corresponds to the malfunctioning system. If you’re not sure which fuse is responsible, use a multimeter to test each one individually.
Step 2: Check the Fuse
If you have identified the fuse, use a fuse puller to remove it from the fuse box. Inspect the fuse to see if it’s blown or not. A blown fuse will have a broken wire inside it. In contrast, a good fuse will have a continuous wire with no breaks.
Step 3: Replace the Fuse
If the fuse is blown, replace it with a new one of the same amperage rating. Be sure to use the correct amp rating to avoid damaging your car’s electrical system.
