Is there a fuse box under the hood of Ford F250 truck?

No, the Ford F-250 (and most modern vehicles) does not have a fuse box *under* the hood in the traditional sense. While there are power distribution centers (PDCs) under the hood that contain fuses and relays, they are often more integrated into the vehicle's electrical system and not easily identifiable as a "fuse box" like older vehicles. The F-250's main fuse box/PDC is usually located inside the passenger compartment, often under the dashboard. There might be smaller fuse boxes or relay centers located in other areas under the hood, but these are less common and usually for specific components.
