5v square tach pulse?????

[slideways]

Just got my new replacement igniter from EMS, and the new design doesn't have a tach output from the igniter.:crying:

So how can i get a 5v square wave tach pulse from the igniter/4 bosch coils?

This is what I thought, but wanted to make sure that it works. Also which diodes do I use?

1N4004 should be fine.
