jdm engine

I have a 90 tsi and my engine is a jdm engine with a water cooled oil housing and a 91+ coil. My ecu is a 90. how do i get the tach to work im hooking up my afc and i need the tach to work. Is there anythin I need to bypass to make it work?

you need the tach adapter from your old 90 coil pack... just wire it into the 91+ coil pack and off you go.
