Vacuum lines or heater core line?

After lots of searching I still cant find what this should hook up to, there's hot air coming out when the car is running. Its just below the passenger side header. I would guess it hooks up to the heater core or has something to do with smog? Any advice on what hoses connect to this line would be greatly appreciated!

That reminds me of the oil cooler lines.
Have your coolant hoses been re-routed?
If so, and without the coolant diverter box, you'll have coolant running through your heater core at all times.
