    Looking for fuse box location

    • There is no central fuse box like on a civilian car, but there are some individual circuit breakers and fuses. Here are some that I can think of off the top of my head:

      • Self-resetting circuit breakers mounted on the firewall on the driver’s side. Inside the engine compartment. They are individual devices, usually oval-shaped, with two wire connections on them. I don’t remember whether there are any under the dashboard.
      • Fuse in the in-tank fuel pump. I think it’s up on top, but I’m not sure because I haven’t had to replace one before.
      • If the truck has had special equipment installed, there may be other self-resetting breakers and/or fuses for that specific equipment.
      • If the truck is a shop van, then there are fuses for the AC wiring inside the van box, on the front wall, on the passenger side.

      That’s all that I can think of off the top of my head.
