Misplaced line=EVAP

Alright I've started to pull the EVAP code and knew that one of my lines were off somewhere. So tonight I pulled the battery and found this line that I'm not really sure where goes to. If you look on the firewall to the farrrthest left(passenger side) it's the last line comming in. The only extra places I have open are two connections on the side(somewhat underneath) of the intake manifold and everything is plummed up just fine. Please help. I would just try those connections out but I don't want to mess something up. THanks!

Update: Alright I removed the battery so I could get a good view of the area and I found one connection that runs off of some lines from the throttle body that was just empty. It pretty much came directly off the middle throttle body connection(F I think?) so I'm assuming it was important and most likely the right connection. If anybody can verify this then that would be awesome. Thanks again

I always have to look at the vacuum diagrams in the haynes/chilton to firgure out the EVAP shit.

I had one line on that POS that kept blowing off making the car .5 seconds slower in the quarter. Everytime I put it back on, times dropped right back fown .5. So I shitcanned the whole setup ;)
