Default Steering column extra black ground wire to column?

During my weekend project I removed the steering column to make some repairs -(and pull the brake booster), I bought a new multi-function switch from AC Delco. It is identical to the one that is in the car except there is an extra black wire in the cars ignition switch harness- it is a black wire that grounds to the steering column. It looks factory, the new Delco harness is a blank pin there. Anyone know, what that's about? Is is a 90 only ground for the airbag?
