2008 Trailblazer - Disconnected wire

I recently replaced my Throttle Body and in the process noticed this disconnected cable in the attached photos. The cable is Purple with a white line and leads back the the firewall on the drivers side.
Any ideas what this wire is for and where it connects?

Thank you. I suspected it may have been aftermarket from the alarm system but wanted to confirm.
