vacuum line

I have a vacuum line (1987sec) that runs from a siemens part atop the drivers side fender (ignition module?) to somewhere near the distributor. It is unplugged and I can't seem to locate where it belongs, or if it's broken. The siemen's part has two round rubber covered plugs, plus the aforementioned vacuum line.

I can't help you, but if you post more useful info, someone could probably help you. Try posting things such as what color the line is. Pics help, too.

The piece on the fender is the ignition module. It uses vacuum and other inputs to determine engine timing. The other end should connect to the intake manifold.
