2023 Fiat 500 312 Fuse Box Diagram

Fiat's body-computer fuse box for the 500 hatchback and the 500C is mounted under the fascia on the driver's side, next to the pedals and to the left of the steering column, behind a cover that is simply pressed into place; the puller for the small blades is stowed on the inside of that cover.

Fourteen MINI positions are laid out in two rows of seven, drawn as plate F0S0172 prints them with the harness connector to the left. Nothing in the layout or the ratings has moved since the 2016 facelift, and the assignment runs on to the end of the type 312's production at Tychy: 48, 43, 36, 38, 53, 32 and 12 across the upper row, 47, 31, 49, 37, 51, 50 and 13 across the lower. Four of those numbers carry no rating, because the handbook prints only the fuses an owner is allowed to replace.

The engine-bay junction box sits on the right of the compartment against the battery, under a cover with a captive screw at its lower corner. Press the screw home, rotate it anticlockwise until it resists, release it, and the cover slides up and out of its guides.

Drawn portrait, exactly as Fiat's plate F0S0607 prints it: the MINI column to the left, the MAXI column next to it, the labelled relay housings in the centre, and at the right the MINI trio F11, F17 and F22 with the larger F08 (climate blower, 30 A) and F85 (front power socket, 20 A) beneath them. Neither the layout nor the ratings changed through the last model years of the type 312, and the numbers moulded into the cover still match the plate. Positions the handbook does not rate protect the engine, gearbox, braking and steering systems, and are dealership items.
