There's two wires listed for tach here:

You can pull up wiring diagrams here (bookmark this page):

Scroll down to page 3 for the ignition coil.
You need 2 diodes and a resistor to sum both of the coil driver wires. Connect the cathode of one diode (striped side) to the black/grey wire at the coil (pin 3). Connect the cathode of another diode to the blue/grey wire at the coil (pin 1). Connect the anodes (sides opposite the stripes) together. From there, connect a resistor (300 - 1000 ohms) to a 12 volt ignition source.
Connect your tach wire to the joint between the resistor and the diodes.
