i'm not 100% sure but it might not work with it at all.
the reason i suspect that is
when i have read the advertising on the repo tachs
it says one of the features is that
they will work with aftermarket ignitions that won't work with a original tach.

If you're using electronic ignition, the tach electronics has to be reworked. I had my gauges and tach converted and compares reasonably well with a digital timing light. That's why the repro tachs work...because they have converted them.
