You have a stock tach ? Or the tach wire as described in the manual ?

As I recall it's the blue wire on the distributor, I spliced it and away I went. I have the old dizzy in a box if you wanna see it.

And today, apparently, I ate my 4th distributor.

just get a wire tap and tap the blue wire going to the back of your stock tach. they will both work then. if you want you can run a wire all the way out to the dizzy if you like
