Restore a clean, secure electrical connection with the Standard Ignition Connector S-1148 (also written S1148), a factory-assembled pigtail that joins the vehicle wiring harness to the component it serves. It is listed under several names — Ignition Switch Connector, Power Steering Pressure Sensor Connector, and A/C and Heater Switch Connector — and is cataloged for the front left / left position. It drops in across a wide GM range, including the 1997-2005 Buick Century, 2006-2008 and 2010 Buick Lucerne, 2003-2008 Cadillac CTS, 1997-2008 Chevrolet Corvette, 2004-2012 Chevrolet Malibu, 2005-2009 GMC Envoy, 2000-2005 Pontiac Bonneville, and 2007-2009 Saturn Aura — 91 applications in all; see the Buyer's Guide tab for the full list and engine details.
If a corroded, melted, or broken original connector is the cause of an intermittent or lost signal at the switch or sensor, this replaces it.
