If you have a Multi meter, like the one I Have, this one:

then you can just see which wire coming out of the Ignition Control is the tach signal.

If not, take it to a shop that does have one, or find someone the wiring diagrams.

if some one knows said wire it would be more helpfull than a shop or gm tech. the ones around here are not the best at wiring solutions.:worthless
