The compact car Ford Focus 2nd generation was produced in 2004, 2005, 2006, 2007, 2008, 2009, 2010 and 2011 with both gasoline and diesel engines. During this time, the car underwent restyling once, which affected the interior and exterior. In this publication, we will show a description of the fuse blocks and relays of the Ford Focus 2, their locations, diagrams and photos. We will separately note the cigarette lighter fuse. And finally, we will offer complete electrical diagrams of the car for download.
