where does this plug into? *urgent*

I did the whole SAI surgery and everytime i looked at the diagram it was confusing. I actually kept the old connections intact and had to go back to it for reference when installing the new parts. I think I need to grow more brain cells.

Check all the Y and L tubes (rubber, not plastic ones). SOme disintegrate at the joints and cause leaks as I found out.
