Have you tried to reset them?

I did the reset, I also disconnected both hids. It does not have mileage or time but the lights turn on. As the the F1 it does not turn on with the switch placed in the on position I think that's normal.
I would say find someone with the same gen busa and put their gauges on to see if theirs work on it. The lights work because they turn on with their own specific pin tied into turning the key to the on position. I doubt the whole gauge would go bad because there are so many different signal wires. Have you done any wiring work near the ECU?
