How it works
This part is in our inventory and ready to ship. Share your VIN and we confirm fitment before you buy, then we’ll call you within about 30 seconds with your quote — or email it if we can’t reach you.
Signs your fuse box has failed
- Melted or discolored plastic around a fuse or relay cavity
- Fuses test good but the circuit is dead until you wiggle the box
- A fuse that keeps blowing with no short found in the harness
- Green or white corrosion on terminals, especially on the cab-side box
- Intermittent ignition, fuel pump, wiper or headlamp circuits
- Burnt-plastic smell under the dash or from the engine-bay junction box
Before you order
- Fuse boxes differ by cab, option package and model year — send your VIN and a photo of the box’s part-number label (or a wide photo of the box itself).
- Note which circuits are affected; on some trucks the interior and engine-bay boxes are separate parts (we stock both).
- Find and fix the cause of any melted terminal — an overloaded circuit or an aftermarket accessory tapped into the wrong feed will damage the replacement too.
- Relays and fuses ship with the box as the donor had them; verify amperages against your owner’s manual before starting the truck.

Frequently asked questions
Do you sell used Fuse Box for all medium-duty truck brands?
Yes — we carry used fuse box units for Isuzu, Ford, Chevrolet, GMC, Ram, and Mitsubishi Fuso medium-duty trucks, not just the Ford F-550.
Is this used Fuse Box tested before it ships?
Yes. Every fuse box we sell is inspected and tested before it ships, so it works right the first time.
How do I order this Fuse Box?
Request a free quote above or call us. Share your VIN and we’ll confirm exact fitment, then call you back with a quote in about 30 seconds — if we can’t reach you, we’ll email it instead.
Do you offer a warranty on this Fuse Box?
Yes — used electronics like this fuse box are backed by our warranty, a category most sellers exclude entirely. Exact terms are confirmed on your quote.
Do you ship this Fuse Box nationwide?
Yes — we ship to all 48 contiguous states with tracked delivery. Most parts arrive in 3–7 business days; engines, transmissions and axles ship freight and typically arrive in 5–10.
Does a used fuse box come with the fuses and relays?
Yes, as pulled from the donor truck. Verify each fuse rating against your manual before use — a previous owner may have changed one.
Can I just replace the burnt terminal?
Single-terminal repair kits exist for some boxes, but once heat has softened the plastic the terminal will loosen again. A complete inspected box is the reliable fix on a truck that has to earn money.
Is a used electronic module covered by a warranty?
Yes. Electronics are covered under our warranty — a category most used-parts sellers refuse to warranty at all. Programming, where your truck needs it, is the buyer’s responsibility unless agreed on your quote.
