2.5/2.7 hybrid help (extra vacuum line?)

[truegearhead]

Long story short. I blew up my 2.5, bought a 2.7 and am transferring all of the 2.5 electronics, manifold etc, onto the 2.7. So far its gone smoothly with the exception of an extra line on the 2.5 that the 2.7 doesn't have. I can't figure out where it used to connect on the 2.5 and can't seem to figure it out on the interwebs either. Does anyone know what this is? I'm hoping I don't have to take the 2.5 apart and move this part over. The last photo shows where it is missing on the 2.7

My blown up 99' 2.5 does not have that pipe either. What did it connect to?

I just finished this exact swap also

You can thank member 78F350 for this, It is a coolant line that was replaced on later engines by a line on top of the oil cooler.
