Default MSPNP gen1 A/C control

I have a 90 Miata running on the Gen 1 MSPNP. I want the a/c condenser fan to come on when pressing the A/C switch but it does not work. I am thinking of just wiring the fans in parallel since the main fan works fine but I like using the condenser fan on a switch like I did with the stock ECU.

Any ideas? The wiring is connected the same as it was before the ECU/engine swap.

The same output triggers both the condenser fan and a/c compressor at the same time. Mazda tied them together on the 1.6 cars.

The entire A/C system is pulled...compressor, condenser, evaporator, etc. However, before I installed the MSPNP the fan would still come on when I pressed the button.
