I didn't pay attention to the fact that the J723T power stage was for 6 cyl - I found that the tach signal from it doesn't work with my tach either. Added the relay with transistor - 86 to +, 85 to tach feed, 30 to ground. I still have the stock powerstage wired, so powerstage pin 1 feeds into the tach circuit via the original coil (1) terminal. I didn't need to add the EZK pulse signal. Without the ground, the tach didn't seem to register correctly. Have to tidy up all the wiring now.
