So I only took the display off and didn't disconnect anything but the hall sensor and phase wires. Green, blue, yellow in that order. I took it out today and rode 43 miles at various speed, it still makes noise but runs perfectly. I also just updated the firmware but haven't had a chance to test it further, the humming comes and goes perhaps louder after it warms up. I'm going to try and get some sound clips with the 360 cam this week.
