My SW tachometer is a different model but the color coded wiring is probably similar: Black=Ground, White= +12V, Green= Trigger In.

Paul;

I will attach an illustration from my SW tachometer installation manual. It shows that the green wire can connect to a coil or to the output of an ignition box. Mine is driven by a Crane HI-6 ignition.
