Hi Tjmac,
I got some help from Sean seandepagnier@gmail.com the person running the pypilot project. I purchased his device see link below and connected that to the Rpi. The advantage in this for me was I had a display I could look at while testing and setting it all up and then I could connect it to the Rpi and have it all show up in OpenCPN/Open Plotter. I soon hope to have it show up on Navionics on the tablet and the Garmin at the wheel.

His device comes with the input jack for the plug that comes with the Davis instrument or you could wire the device yourself as I did. I only did this because I used the existing wires and mount to the old windvane.
Wiring:
brown - 5v
gnd - 0v
blue - wind speed
white - wind direction
Based on:

Good luck and let me know if I can help in any way.
