The 2nd generation Ford Focus compact car was produced in 2004, 2005, 2006, 2007, 2008, 2009, 2010 and 2011 with both gasoline and diesel engines. During this time, the car was restyled once, which affected both the interior and the exterior. In this publication, we will show a designation of the Ford Focus 2 fuse and relay boxes, their locations, diagrams and photographs. Separately, we note the cigarette lighter fuse.
The current fuse assignment may differ from the one shown and depends on the year of manufacture and the country of delivery for Ford Focus 2. Check the designation with the diagram on the back of the protective cover. And if you have the wrong generation of the model, see here: Focus 1 and Focus 3 .
