I have a 2007 PRS Alpha controller with 4 motors and cables for sale. The controller wiring diagram is located at this Link. The controller has been connected to a computer running the latest software and the firmware has been updated to the latest version. The motors work as they should.

Asking $4000 OBO + shipping from 54656
