does anybody knows where this hardline supposed to hook into?

that is for the egr valve. look on the emissions label on the hood for the vacuum diagram. the hard line goes to the single connector of the first photo. the other 2 connectors on top goes some where else. the emissions label should show where the vacuum lines should go.
