Repair a corroded, melted, or broken wiring connection with the Standard Ignition Connector S-2173, a factory-assembled pigtail cataloged as a Door Ajar Switch Connector / Idle Air Control Valve Connector / Courtesy Lamp Switch Connector. It provides the harness-side plug that mates to the switch or valve so the circuit can carry signal or power again. It's a direct-fit replacement for the listed applications, including the 1999-2003 Ford Windstar, 2003-2015 Mazda 6, 2004-2010 Ford Focus, 2004-2021 Mazda 3, 2005-2012 Ford Escape, 2006-2012 Ford Fusion, and many more — see the "Vehicles it fits" section for the full list.
- OE-standard build: manufactured to meet exact OE standards in TS16949- and ISO9001-certified facilities, and designed for specific vehicle applications.
- Tested for reliability: connectors go through quality checks and rigorous testing at every stage of production.
- Factory-assembled for easy install: ships as a user-friendly, factory-assembled connector with wire connectors and, where applicable, extended lead wires, so no specialized tools are needed.
Because one connector body serves several circuits, this S-2173 is listed under all three names above. If a damaged connector at the door ajar switch, idle air control valve, or courtesy lamp switch is the cause of your electrical fault, this replaces it.
