The Ford Ka compact city car has been produced across three generations since 1996 for global markets. First-generation production years: 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, and 2007. The second generation was manufactured from 2008 through 2016 (2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, and 2016). The third generation model has been sold in global automotive markets from 2017 to the present. This article detail fuse and relay box locations, circuit diagrams, and assignment descriptions for first- and second-generation Ford Ka models (chassis codes BE146 / B420), along with the general placement of electronic control units (ECUs). The cigarette lighter fuse is highlighted in bold.
Fuse and relay assignments may vary depending on the model year, equipment level, and regional specifications.
