Is there a way of making a systems check tach work on a non systems check tach system? I don't have the plug for the back. Anyone have a wiring diagram for the plug? I'm not interested in making the check lights work, just the tach.Thanks

PINS 1, 2 and 3 will run the tachometer.

Thanks Ezeke,Exactlywhat I needed. Do you know if pins 1,2,3,4 are across the top row if looking at the back of the tach (with the gauge in the correct mounting position)?
