Steve,
I checked out the line going through the tunnel and over the trans. There are two lines running parallel to each other. One is a cable and the other is a vacuum line. The vacuum line is black with a green stripe along the side. It is connected at the trans to the modulator. The other end is connected to what appears to be a solinoid that is mounted on the firewall. I sucked on the firewall end of the line and the line holds a vacuum so I assume there is no "Y" connector that is out of sight and inside the tunnel that my mystery vacuum line might connect to.
There is a second line comming from the solinoid that goes up behind the brake booster and is connected to some yellow pots. The vacuum for the green striped line comes from these pots and then goes to the solinoid on the firewall.

So it appears as though my mystery line... black with white stripe must be for something else... Unless I got the lines switched somehow during my struggles with the starter.

Possibly you could take a peek under the hood to see if indeed the green striped line comming from the trans mounts to the solinoid on the firewall.

Many thanks for your input.
