Engine compartment fuse box (power distribution box)

On the driver's side of the engine compartment, behind the brake fluid reservoir and next to the battery: release the cover latches and lift the lid, which carries the numbering plate on its inside. Drawn from plate E330939 of the 202101 manual, 58 numbered positions, the box seen from the fuse side with the fuses standing on end and their numbers printed sideways. Three groups of fuses sit around three round openings in the moulding; the openings are cover and mounting features, not relay sockets, and the Bronco's relays are not printed on this plate at all. M case cartridges are drawn with the M case body, Micro 2 blades with the smaller Micro 2 body.

Body control module fuse box (passenger compartment)

Low under the driver's side of the instrument panel, next to the brake pedal and left of the steering column: the trim panel along the bottom edge of the dash pulls towards you and swings down to expose the box. The launch manual (edition 202101) prints plate E145984 with the 30 A circuit-breaker socket 38 alone at the left-hand end, then the Micro 2 rows 1 2 3 and 4 5 above 23 to 28, where 26 sits in the column the upper row leaves open. The taller Micro 3 bodies follow in two ranks, 7 9 11 13 15 and 18 20 22 over 6 8 10 12 14 and 17 19 21, with 16 standing between 15 and 18. Positions 29 to 37 run along the bottom, 34 under 16. Rows read left to right. Each Micro 3 body carries two fuses, drawn as its two halves with the upper number on the upper half; 38 is an empty breaker socket, not a fuse.
