Help with MS3x & FFE trigger wheel new install

Hi,
I have a new ms3x v3.57 install using a FFE 36-1 trigger wheel and hall sensor that wont fire.

Im not getting a signal from the FFE wheel / sensor. Setting are per FFE instructions: Toothed, Falling edge, single wheel - missing tooth etc

The sensor is wired as follows, using shielded cable that came in the loom from DIY Autotune:
Signal -> Pin 24 (Main board)
Ground -> Pin 2 (Main board)
+12v -> Switched 12v

Is this wired correctly?
Do i need to change/set the jumper up differently?
Or adjust any pots?
Anything else that need to be setup or changed?

Thanks

IIRC I had to wire them backwards to get the two I have done to work.

I am about 90% positive it was awhile ago.

wierd, the pots affect the hall signal? I thought they were for tuning VR only.
