Module to get stock tach/rpm gauge to work with Holley?
I know there were a bunch of people working on this and some vids of people getting it working on YouTube. Did anyone actually get one done that allows your factory rpm tach to work with the Holley Terminator X?

the dash only takes in a square wave. its red 10 on the factory ecu. the cam sensor has nothing to do with it unless youre using the factory pcm to drive the tach.
