If you've got 5 good wires coming down the mast
you can use them for your wind.
I recommend getting a Raymarine
ITC 5 converter. It will take input from most older instruments and devices -wind, depth, autopilots, etc and convert the signals to NMEA 2000
This allows you to use any of the modern displays, both B&G, Simrad
to display data. A Raymarine i70 display can be set up to display depth, position, wind angles, speed, etc. and switched around on the fly.
