I have a Defi tach with the control unit, The power and the illumination is wired up no problem. I tried to wire up the tach signal to the ecu, nothing. Then I read about how the digital ignition systems do not send the correct signal. So I bought an MSD tach adapter. Tried hooking it up to the coils like they said to, and nothing, then tried hooking it up to the ecu and nothing still. I am lost!!!

1989 240sx Fastback

Please Help!!!
Ive searched and havent come up with squat!
