In this article, we consider the seventh-generation Ford F-650 / F-750, produced from 2001 to 2015. Here you will find fuse box diagrams of Ford F-650 and F-750 2004, 2005, 2006, 2008 and 2011, get information about the location of the fuse panels inside the car, and learn about the assignment of each fuse (fuse layout) and relay.
Fuse Layout Ford F650 / F750 2001-2015
Information from the owner’s manuals of 2004, 2005, 2006, 2008 and 2011 is used. The location and function of fuses in cars produced at other times may differ.
Cigar lighter (power outlet) fuses in the Ford F-650 / F-750 are the fuses №104 (Power point) in the battery junction box (Engine compartment), and №3 (Cigar lighter) in the central junction box (Passenger compartment).
