I have a faze tach, I have everything but they little black box? the power supply that goes to the dimmer circuit for illumination. I have tried to get the tach working by running 12v into the reciprocal that the black box hooks to...


So i was wondering if any of you have one of these tachs and could let me know just what the power supply does?

like its output power 5v 200mh?
Crap like that.
i cant run the damn thing without it?
