The upfitter relay on a 2011 Ford F250 is a crucial component that provides power to various accessories and equipment installed by the vehicle owner or a third-party upfitter.

Where is the Upfitter Relay Located?


The upfitter relay on a 2011 Ford F250 is typically located in the engine compartment, near the battery or the fuse box. However, the exact location can vary depending on the specific model and configuration of the truck. Some common locations include:

  • Near the fuse box, on the driver's side of the engine compartment

  • On the firewall, on the driver's side of the engine compartment


It's important to note that the location of the upfitter relay may also be affected by any additional accessories or equipment installed by the vehicle owner or a third-party upfitter. In some cases, the relay may be located in a different position to accommodate these modifications.
