Keep your Ford E-Series (2015–2020) operating efficiently with this detailed fuse box, fuse panel, and relay guide!
The cigar lighter/power outlet fuses (all are located in the Engine Compartment Fuse Box ) in the Ford E-Series are:
Fuse №65 : Power Point 2 (Glove Box)Fuse №66 : Power Point 3 (Cutaway B+)Fuse №67 : Power Point 1 (Instrument Panel)Fuse №72 : Cigar Lighter / Power Point
The fuse panel is located to the left of the brake pedal and mounted onto the lower left cowl panel.
The power distribution box is located in the engine compartment.
