    Ive searched on here some and i can't seem to find out where exactally the tach wire is supposed to connect in the ignition system. Ive had a tach sittin around for a few weeks now and wanted to go ahead and get it installed...where exactally does the tach wire go tho?

    On most aftermarket tachs, the green wire go's to the positive side of the coil. HEI dist have a hook up for the tach next to where the batt. wire connects.

    thanks JJ, you made my 350tbi-454 carb swap that little bit easier.

    not to hijack, but i have a HEI dist. im using, can i just snip the red wire and hook it to the positive side of the HEI dist?
