Need help with vacuum line connection

[fdf150]

I have a 1998 Ford Expedition E.B. Edition 5.4 liter and I have a vacuum line that came unhooked and I can't figure out where it goes. If someone could show me a pic of the nipple that the line hooks to and explain to me how I get to that nipple,I would be very happy as it is causing me lots of problems. Here is a pic of the line,one end hooks to the Y on the PCV,but I can't find where the other end hooks to.Thanks in advance!!

Do you have to remove the plenum to see where it hooks up at?

usually not but I did pull the upper part (5x8mm bolts) for better access to the last one I did
