Replace a worn or damaged connection in the HVAC blower circuit with the Standard Ignition HVAC Blower Control Switch Connector S-781, a factory-assembled pigtail from the Standard Ignition switch and connector lineup. Standard Ignition lists it as an auxiliary blower motor connector, so it is cataloged under both names. It is designed for specific vehicle applications, including the 1968-1972 Ford F-100, F-250 and F-350, the 1980-1985 Ford L800, and Kenworth trucks such as the 1986-2004 Kenworth W900, 1986-2004 Kenworth T600A, 1987-2004 Kenworth T800 and 1997-2004 Kenworth T2000. See the Buyer's Guide tab for the full list of applications.
- Built to exact OE standards: Standard Ignition makes these components to exact OE standards in facilities certified to TS16949 and ISO9001, each designed for specific vehicle applications.
- Tested throughout production: Every connector goes through thorough quality checks and rigorous testing at each stage of manufacturing.
- Simpler installation: The connector arrives factory-assembled. Wire connectors and extended lead wires are supplied where applicable, and the design does not require specialized tools.
- High-grade materials: The materials are selected for strong conductivity and secure connections.
The S-781 draws on Standard Ignition's decades of research and development focused on what technicians need. It is one of hundreds of pigtails and sockets the brand offers for nearly every electrical job. When the original equipment fails, Standard Ignition's connectors are designed to address the inherent failure issues. Signs this connector may need replacing include corroded, loose or heat-damaged terminals and a blower that cuts in and out. If a damaged connector is the cause, this part replaces it.
