Hi all, I was installing a new O2 sensor in my 05 Lacrosse this morning. When I was done, I looked over the rest of the engine compartment looking for oil leaks, etc. I noticed a wire connector underneath the master cylinder not connected to anything. It looks like it never was connected to anything. I'm attaching a pic of it. I'm guessing it's for a feature my car doesn't have. But, to be sure, I thought I'd ask the community.

Possibly same harnesses used for AWD & FWD. AWD has speed sensors in the wheels that detect slipping, is my understanding. Just a guess but sounds as mystery harness may extend underneath.
