1995 GMC Rally G2500, 4.3 ZSECTION Scrapped Vehicle

Some vehicles which have to be scrapped may have undeployed SIR systems. When scrapping a vehicle with an undeployed module:

Turn ignition switch to OFF position. Remove SIR fuse. Disconnect Yellow 2-pin connector at base of steering column. Cut harness side of SIR wiring approximately 3-6" from Yellow 2-pin connector.
Splice 2 wires at least 20 feet long to wiring cut from SIR harness. Connect Yellow 2-pin connector.
Ensure inflator module is secured to steering wheel. Remove all loose objects from front seat, and ensure no one is in vehicle. Stretch wires away from car as far as possible.
Connect wires to a 12-volt battery. Air bag should deploy. DO NOT touch inflator module area for 20 minutes due to heat generated during deployment. Wear gloves and safety glasses before handling deployed air bag. Wash hands with mild soap and water afterward.
On vehicles with passenger-side air bags, repeat deployment procedure for passenger-side. Access Yellow 2-pin connector at base of right instrument panel (behind knee bolster) or behind glove box door assembly.
