Default Need help with 88 vacuum lines

There's a small cannister looking T fitting for 3 vacuum lines on the driver side of the distributor on my 88. Yesterday after i got done with new cap/rotor/coil i noticed the one coming off the top was not connected to anything and i can't see anywhere it might go. This round tee had a line coming off the bottom going to the passenger fitting on the plenum, the middle line goes to a tee on the driver wheel well where it eventually goes to the cruise control. Then there's the line coming off the top, which i'm not sure about. If anyone has info on what the line connects to it would be greatly appreciated.

Thanks ...

Goes into the wire harness that goes inside the car. Its the vac control for your heat/AC/defrost. Look for the harness behind the distributor, you should find the plastic line there.
