Couple of mysteries

[VABird]

Had my "new" '06 apart  doing some checks and maintenance before the serious riding starts and found a couple items that I don't know about. There was a plug that went nowhere that was soon identified via schematic as going to the purge control valve; part of the evaporative canister that... is missing. But there's also what appears to be a vacuum line from the ECM that would reach to where I presume the canister would be if there was one; near the fuel pump connector. Is that what it is? (pic#1) Also, there is a hose connector on the right side of the airbox toward the rear (pic#2) that appears to do nothing. Another part of canister?

Please no replies that say "I'm no expert, but here's my guess...."

No guessing, that is the Barometric sensor hose and should go to that white connector on airbox

Thanks. I should have put that together!
What's the hole near the white connector on the airbox?

You should be able to see its blanked off, not used at all.
