how do I identify this CDI unit ?

[Team Reel Warriors]

I have been searching for hours trying to identify a cdi unit a friend gave me. I ran the numbers on the face of the unit, but no info comes up on those numbers. Any help identifying this unit would be very appreciated.

Here are the numbers: 66K-01
F8T33773 -------------- Thank you !
1912

66K would be a VX200, VX225
