Breather vacuum lines

Hello Again;
After having my ride down for several weeks...I have her back together. I took lots of pictures as I tore into her...but unfortunately I didn't start till I had the breather off. Under the breather, towards the front end are two nipples side by side. Does it make any difference which one the vacuum line goes to? I think that I had only one line going to it. If there are two...can anyone explain what goes where please? I'll start anew and trace everything out to make sure I've done it right.
Thanks Folks
Fred

Generally there is an emissions label under the hood that will show where it goes. Is that still there? I can post you the diagram needed,if you tell me the year.
