sorry about the use of words and thanks, I believe the Ignition control module (ICM) and igniter refer to the same thing. My car Vin AL7.011866 is an 87 model, the igniter is on the coil bracket, so I believe the system should basically be the same with little variation. I need (1) to identify the pulse wire from the control unit under the steering to the igniter at the coil.(2) the wires from the ignition coil to the igniter and tachometer.
