Well, I am not making much head way with this tach. Apparently, with this a non-OEM type tach and cannot locate any documentation on it.
Is there any tricks I can do to figure out the wiring; like with a ammeter or another tool - without arbitrarily just hooking up wires (I would hate to blow this up!) ?
