This Saihisday replacement kit matches factory-fit connectors and replaces the internal control board for models that use part numbers such as 904-229, 3C3Z12B599AARM and 1845117C2. The kit is created to be a practical repair option for owners and technicians who prefer restoring the existing module instead of buying a complete factory unit.\u003c\/p\u003e\n\n\u003ch3\u003eWhich vehicles and part numbers does this FICM repair kit fit?\u003c\/h3\u003e\n\u003cp\u003eThis kit is intended for Ford Powerstroke 6.0L applications including F250, F350, F450, F550 (2003–2007), Excursion (2003–2005), and select E-Series vans (E-350, E-450).
