Wiring help

So I'm trying to fix the hack job mess from the guy that had the car before me. I'm switching to a one wire alternator and msd ignition.

So I know the voltage regulator and ballast resistor get eliminated with the one wire alternator, and the old ignition module is eliminated with the msd, and this is the only thing I can find as far as the ignition module but I've never seen anything like it, it has a pentestar with part number but a search didn't show anything.
