i recently bought an air bag for my 99 civic si. come to find out that the yellow plug on the air bag does not fit into the smaller white plug in the dash. i was wondering if there is supposed to be another component which plugs into the small white plug in the dash that the yellow plug on the air bag plugs into as well. what is an air bag module? could this be what is missing? please help anyone that has or knows about the passensger air bag in a civic...
