The Ford Focus Mk2 (2004-2011) uses a central passenger-compartment fuse box and an additional engine-compartment fuse box. The exact engine-bay assignments vary by engine and specification, which is why the source article retains two separate engine-box tables instead of forcing them into a single layout.
The complete tables below preserve every source row, including positions marked not used and the separate Focus ST, diesel and convertible variants.
Some electrical architecture from this period is shared across Ford’s C1-platform family, including the Ford C-MAX Mk1 and the later Ford Kuga Mk1, but fuse numbers and equipment assignments should always be checked against the specific model.

FAQ – Ford Focus Mk2 fuses
Where is the cigarette-lighter fuse?
Central fuse 39 – 20 A also protects the rear power socket.
Which fuse protects the diagnostic connector?
Central fuse 44 – 10 A.
Where is the fuel-pump fuse?
Central fuse 51 – 15 A.
Why are there two engine-compartment tables?
The source article preserves two European-manual configurations. Version 1 is a shorter Polish-manual list; version 2 is the fuller English-European list with additional engine and body-style variants. They are intentionally kept separate.
Why do some numbers appear more than once in version 2?
Ford uses different assignments or ratings for specific configurations. Examples include F9 for Focus ST, F17 for convertible models and F33 for gasoline, diesel and Focus ST variants.
Can the Focus Mk2 table be used for the C-MAX Mk1?
No. The vehicles share some platform architecture, but fuse assignments must be checked separately for each model.
