1994 Vortec CPI replacement

Finally decided to tackle this job to fix a bad miss my truck developed. It isn't a bad job but I found some loose or unattached vacuum lines that I could use help identifying. One is a line with 2 branches, one of which plugs into the back of the CPI intake plenum. Where oh where does the other branch connect? The other is a super thin (1/8"?) line that didn't appear to be connected to anything.

See pictures at the following link. Any advice greatly appreciated.

I found a source for the CPI unit on the net at Lindertech.com. They have reman units for $229. Is this the going rate? Any other good source for these parts?

I guess I have to reply to my own post to say that the job is done and the truck runs great. :-)
