1. So once again either right click in the blank Channels pane and select Add Channel from the little pop up menu, or click the gray gear with the green plus + sign next to it on the top menu.

3. Then double click the Channel you want.
Note:
We only typed "vacuum" yet it still found Manifold Vacuum. Cool stuff!
