Which vehicles does it fit?
It fits the 2000-2011 Ford Focus, 2010-2013 Ford Transit Connect, and 1999-2003 Mazda Protege. Check the Buyer's Guide tab to confirm it matches your vehicle.
What are the signs this switch may have failed?
Common signs are the engine not cranking in Park or Neutral, reverse lights that stay off, or the engine starting while in gear. Diagnose the cause first, as these symptoms can have other sources.
