Hi all! Newbie owner attacking the replacement of my height sensors on my 2011 L322 RR. While looking around and enjoying my “one sensor down glow” I noticed a connector flopping about. In the drivers side wheel well. Posting a pic. Can anyone identify this? I’m stumped. ABS/Speed? ??? Help!

Looks like the vent hose for the front differential.
