The DIS module on the intake manifold has like 6 wires coming out of the bottom of the module and the far right wire, which is black with yellow strip or yellow with brown is the signal wire for the tack. You need to splice the green wire from the tach to this wire, and then hook up the red to a postive when key is on, and black to a ground, and then the white is for the light which goes off the headlights.
