Subject: Tach signal off of 2nd gen igniter

Do you know what the signal looks like on the 2nd gen trailing plugs  igniter wire labeled tach yellow with blue tracer?


I would like to use it for rpm input to an Arduino controller engine monitor.


Is it a 12 volt pulse?  2 pulses per rev?

Thanks for any help
