Every manufacture has different procedures for disabling the air bag system but here are two simple steps that should do the trick. 1) Find and remove the air bag fuse. 2) Find and disconnect the air bag inflator module connectors for the drivers side air bag and passenger side air bag if equipped. The connectors should be yellow in color. The drivers side would normally be located at the base of the steering column and the passenger side connector should be located under the right side of the dash. If you need more help a repair manual may be the answer. DIY repair information is available online from AllData - www.alldatadiy.com.
