Where is the fuse for f250 trailer wiring?

The location of the fuse for your F250's trailer wiring depends on the year and model of your truck. There isn't one single location. It could be in the underhood fuse box, the passenger compartment fuse box (often under the dash), or even a separate trailer tow module fuse box.

To find it, you need to consult your owner's manual. The manual will have a diagram showing the fuse box layouts and identifying which fuse is for the trailer wiring (often labeled something like "trailer tow," "tow," or a similar designation).

If you don't have your owner's manual, you can usually find a digital version online by searching "[Your Ford F250 Year] Owner's Manual" on Google or Ford's website. You'll need to know the exact year and model (e.g., F-250 Super Duty XLT, 2018) for accurate results.
