Hey!!

I need some help ..
I want to put a Tachometer on my Foreman ..
I don't know much about ignition system and the electronics of the Foreman ..

It is a CDI system right !? .. Anybody can give me the Voltage before the high-tension coil .. ?
Anybody can give me information they have about the electronics, like if there is a dedicated wire that gives the RPM information
or if there is a pin on the ECU that gives the RPM Output ...

I need this, because I will build my own Tachometer since I know electronics !! ..

Thnks!
