Inflatable Restraint Wiring Harness
WARNING: This page is about a different car, the 2004 Pontiac Aztek and 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.
The inflatable restraint wiring harness connects the inflator modules, the inflatable restraint sensing and diagnostic module (SDM), the deployment loops, and the serial data circuit together using weather-packed connectors. Supplemental inflatable restraint (SIR) system connectors are yellow for easy identification. When repairing SIR wiring harnesses, follow the proper testing and repair procedures listed in the service manual.
