Long time since I have played with one of these if my old brain is functioning correctly that is a vacuum line. It should have a non-return valve in it then connect to the electric emissions valve and from there to the exhaust emissions valve.
But then again, I could be confused at my age 🤣 You can check if you take a look at www.realoem.com put the last 7 digits of your Vin number into the search box, it will bring up your model then look in the engine section I believe. You will find small, exploded drawings which should help identify parts and where they fit.
Good luck
