The green wire on an Apexi tacho goes on the rpm signal wire, but i don't know if this will help your particular tacho.............

The yellow one might be for the background light ???

Did you buy it 2nd hand without instructions or something ?

Is there any letters on the back of the tacho with the wiring ?

Heres an ecu pin out diagram, i guess you'll just have to try and see if it works ..........
