I finally found it! Jim you were right, it went to the manifold.
After looking at another 300, I saw that it attaches under the airflow plate, under the line that connects to the thermovalve. Only probelm is, it didn't help to connect it. I figured that an open vaccum port would help correct poor idle and low manifold vaccum. This one didn't. Anyone know if there is supposed to be significant vaccum at this port. I measure less than 1"hg.
