The end with the hook molded into it goes inside the plastic zip-tie on the firewall side of the air box. It doesn't connect to anything. It is the transmission vent.

you're kidding. that's it. i spent all day trying to find where it hooks up to. damn it. thanks though. saved me a crapload of work. thanks.
