Finally back at putting this thing back together. I've got all of the lines replaced and the manifold reinstalled. Everything is hooked up except one line that I cannot figure out where to connect it to. It's on the back passenger side of the manifold, and appears to be coming out of the top of the "BPT" according to the under hood vacuum diagram. The diagram looks like it goes to a solenoid that I already have hooked up to other vacuum lines. It's possible that I have some of this routed incorrectly.
This first picture is of the underside of the manifold before I reinstalled it, and the second picture is of the mystery hose that I cannot connect...
