So I need to know which wire on the back of the gauges is for the tach signal. In digging around in google I have found that it should be either black, green, gray, or white with a blue stripe. None of those wires exist on the gauge wires except for the green which leads to a bulb. I know the black wire is on the tach, but I've already rewired my whole engine to get the Autronic SM4 computer set up, so no more stock igniter. Anyone have any ideas?

Directly behind the tach gauge are three screws that hold the tach in AND connect the plastic circuitboard wires to the gauge. Screws are ig-, ig+ and e. The letter "e" is behind each gauge. The e's on the gas gauge, speedo, and tach are all connected together. Is this "earth"? IG+ on all of the gauges are connected together, as well as a few bulbs, so this seems like it's the positive wire. That leaves IG-, BUT there are also others. B16 is labeled by the center connector, and connects to the two turn signals and also to the little black connector that unclips from behind the tach. (the connector has transistors inside, and maybe a small chip). A13 also comes out of this little connector and it by itself. The last wire is not labeled and goes through a diode prior to going into the connector.
