INFLATABLE RESTRAINT WIRING HARNESSES

The inflatable restraint wiring harnesses connect the Sensing And Diagnostic Module (SDM), inflator modules, discriminating sensor, and the class 2
serial data circuit together using weather pack connectors. SIR system connectors are yellow in color for easy identification. When repairing SIR
system wiring harnesses, follow the proper testing and wiring repair procedures.
