Does anyone know where the tube coming off the bottom of the vacuum pump behind the front bumper on a 2012 jkus goes to? I put a relocation kit on and have no clue where it goes. Now I hear a noise under my drivers side dash that comes on twice after startup and don't hear it again. I called or-fab but they said it doesnt go anywhere, that it's just for draining. I can't help wonder if that hose went to something related under the dash? I'm stumped. Thank you for any help.
