In this article we take a look at the seventh generation Ford F-650 / F-750, produced from 2001 to 2015. Here you will find the Ford F-650 and F-750 2004, 2005, 2006, 2008 and 2011 wiring diagrams, information on the location of the fuse boxes inside the car and the allocation of each fuse (fuse layout) and relay.
Information from the 2004, 2005, 2006, 2008 and 2011 owner’s manuals is used. The location and function of fuses in vehicles manufactured at other times may be different.
The fuses for the cigar lighter (socket) in the Ford F-650 / F-750 are fuses №104 (power point) in the battery junction box (engine compartment) and №3 (cigar lighter) in the central junction box (passenger compartment).
Fuse box location
Passenger compartment
The fuse box is located behind the passenger airbag cover and can be accessed through the glove box.
Engine compartment
The power distribution box is located in the engine compartment.
