Driver's side Cam Tower vent. This one and the one from the passenger side Y together and then enter one input port of the dual chamber AOS. The metal connector is a one-way check valve to make sure none of the stainless mess separation media in the AOS can be sucked back into one of the cam towers. These hoses should have pressure all the time and never vacuum, but better safe than sorry.
