Replacing CDI

I am working on a 1986 YFM80s Moto4. This will be my daughters first quad. The issue I have after testing the source coil,Trigger coil and ignition coil ia a bad CDI. They are still available but around $270.00. I found a Posh super battle 6 pin CDI for $15.00 new. Has anyone ever wired one of these into a Yamaha? It looks like it will work as long as I learn the pinout and make sure it is hooked up correctly. Any tips I should know?
