Steering Column/Shaft Disaster

Alright, I messed up and ended up loosing control of the subframe with my hydraulic jack when replacing the subframe bushings. It fell a bit more than it should have and ended up dislodging the Intermediate Steering Shaft. Utilized another person to get everything back into place...and this person decided it would be fun to twirl the steering wheel 360 degrees...which of course broke a component of the airbag system in the steering column and turned my airbag light on. I neglected to tell them NOT to twirl the wheel as I'm aware of the warnings. :(

So, my question is: When the steering shaft is not connected to the wheel, and said wheel is turned 360 degrees, what component of the air bag system breaks (which wire snaps, etc....)? GM has enough "warnings" around the protective boots of the shaft...so it's gotta be a known fact right?

The clock spring in the upper column is bad, very common mistake. Care ful working on the SIRS, look up the procedure and precautions.
