Take off the driver's side front tire. Then carefully remove the screws and plastic mollys that are holding the black wheel well in place. If you work carefully you only have to remove those on the half closest to the driver. Now carefully pull this part of the black material away from the fire wall. Underneath you will find a black rubber cap. Pull it off and you have access through the firewall. The vacuum line should be brought off the manifold into the wheel well through a puncture hole you make in the rubber cap and then into the car entering to the side of the fuse box at the driver's feet. In order to replace the rubber cap you may have to first remove the nylon insert which is in the firewall. This is unusual in that it is removed by lifting up on a catch and then pulling on the two halves toward you almost as if you were braking the circumference. Hope this helps.
