Configure Airspeed Sensor on Kakute F7

Hi

I am trying to configure an analogue airspeed sensor and a HolyBro Kakute F7 AIO running AurduPlane 4. When I go to Mission planner it gives me a choice of inputs but they are mainly referenced as APM2 pins.

Which pin/input should I use in Mission Planner and which pin should I connect to on the Kakute F7?

I am happy to use the RSSI pin if this works as I do not need this.

If this is not going to work please suggest other option. I have the compass and GPS working already with the compass on the I2C bus.

Thanks for you help.
