just guessing, but do you have an assembly manual?? i would think it would be there. also you might want to go to corvette central's sitee and see if they have any parts for the system. if they do, they often have a diagram of the entire assembly. it might help you out that way.

Mine starts on the intake manifold just foward of the distributor. Runs through a plastic reducer then a plastic reducer/splitter. One side goes foward - I presume to the lights, the other does a "T" with one line getting reduced to one of the hard vacuum lines. This line goes through the firewall to the A/C and heater controls. The source off the intake manifold also goes down on a metal tube to the transmission on the passenger side of the engine. I'm looking in my assembly manual now and will let you know if I find a vacuum diagram.
