Edit Reason: Interrupt pulse input requirement.

Hi,
Initially, it's probably a "hardware" issue. Provided that 12 volts is sufficient to operate the anemometer (and you're using a 12 input supply/battery) then you should be able to pick up the 12 volts on pin 1 of the Wind connector.
More of an issue is that (unlike some microcontrollers) it appears the Arduino/Atmel architecture uses (some) separate pins for Digital and Analogue inputs, and a digital-only pin (D3) is connected to the Wind Speed input (pulses). In particular, it appears that only two pins are available as the "interrupts" for the Anemometer and Rain Pulses. But it looks as if the immediately "opposite" pin (in the other row of the Nano) is currently an "unused" analogue input (A6).
I'm afraid I'm not yet "up to speed" on the Arduino/Atmel software and hardware possibilities, but I think it should be "possible" to link those two pins on the underside of the PCB and a modification to the software could be "reasonably straightforward".
However, it may also be relevant which Wind Direction sensor you plan to use?
Cheers, Alan.
