Sir,

I converted my Toyota KR42 townace 2002 gasoline(EFI) vehicle dashboard to a Noah dashboard. The earlier one did not have a RPM(Tacoh)meter but the new one.

I need to know how to do the wiring to make this RPM meter to indicate. I think the RPM meter panel wire is connected to the computer (ECU) box straight away. But I do not know from where to take the sensing pulse which is input to the computer box.

Pl tell me the wiring I should do with a diagram if possible.
