If I recall, on the NA6 the tach is dríven from the stock coils.

I believe you'll need to wire the tach to the tach output of the ECU.

The OEM ignitor drives the factory RPM gauge in the gauge cluster... when the igniter is removed an ECU dríven tacho signal needs to be setup and wired to the gauge cluster.
The easiest way to achieve this is to run a wire directly from your aftermarket ECU using the relevant output to the gauge cluster and connect it to the tacho gauge input on the cluster.

Got it working
Thanks to all
If you have a haltech is the violet and black wire
I got a tach signal from the diagnostic port
Yellow and blue wire
Splice it in the haltech wire and job done
