INFLATABLE RESTRAINT WIRING HARNESSES

The wiring harnesses connect the sensing and diagnostic module (SDM), inflator modules, front end sensor, seat belt pretensioners, seat position
switches (SPS), 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.
