I just sent the vacuum diagram.
The plenum is the top half of the intake manifold, the rectangular peice the throttle body attaches too that has ECCS written across it. The vacuum diagram calls it the Intake Manifold Collector. It bolts to the intake manifold, but, depending on what all you have removed already, you may not need to remove it to get to those two long bolts. Hope this helps.
