Elusive tach signal on cb750

Hey guys,

New to the forum but my project is a 1979 cb750f Efi conversion with a microsquirt and a set of gsxr 750 throttle bodies,

I have mounted the computer and the throttle bodies are all set to go other than the fuel rail.

So i was wondering how do I set up the CDI ignition to put out a tach signal?
I know it has been done but i would need to know what resistors and how to wire them up.

Thanks in advance for any input
