2018 Ford F-150 XIII Fuse Box Diagram

The 2018 facelift, which brought the 3.3 L V6, the ten-speed transmission and the 3.0 L Power Stroke diesel, replaced this box outright. Plate E251921 has 105 positions, none of them relay sockets among the numbers, and is laid out as eight columns of horizontal fuses in two halves. The lower half is 1-50 and the upper half 51-100, and in both the columns are numbered from the right-hand column leftwards while each column itself reads top to bottom; 104 and 105 stand on end in the top corners, 102 and 103 on end either side of the relay R02, and 101 sits under the relay R05 at the bottom left. The numbers 7, 9, 11, 40, 42, 44, 57, 68, 90 and 92 do not exist on this plate. The page follows the fifth printing of the 2018 manual (September 2018), in which 61 and 95 are 15 A spares rather than the Raptor HID headlamp fuses of the first printing, 26 is marked for the petrol engines and 48 for the diesel, and 70 covers the ABS valves. The box is under a latched cover on the driver's side of the engine compartment, beside the battery. Micro 2 fuses and M case cartridges are each drawn with their own body.

Position 1 loses its interior-lighting circuit for 2018 - the first printing of that year's manual still listed it, the fifth printing followed here does not. Nothing else in the body control module panel changes, and plate E145984 is the same drawing Ford has printed since 2015. It sits on the right-hand side of the passenger footwell behind the kick-panel trim: pull the trim towards you, swing it out, then press the tabs on both sides of the fuse panel cover and pull it off. The manual prints the plate upright with the circuit breaker 38 at the top; this diagram rotates it, putting 38 at the left. The rows then read left to right: 1-5 with a gap between 3 and 4; 23-28; nine columns of Micro 3 dual fuses, the odd-numbered element always the upper one (7/6, 9/8, 11/10, 13/12, 15/14, 18/17, 20/19, 22/21) with 16 standing on its own between 15 and 18; and 29-37 across the bottom. Each Micro 3 body shows its two numbered halves, and 38 as a 30 A plug-in breaker with a MAXI body.
