    You'd get the signal from the - side of the coil. I forget which color wire, but its not the red/green one. Its the other wire.

      it should be (on my sunpro tach anyways...): red-power, black-ground, white- switched 12v+ source, and the green-coil signal wire, tapped into the negative side
