Here's the part I don't understand on the fix. The center pin only goes hot when reverse is activated. It can feed back to the controller if it shorts to the hot for the brakes when reverse is activated, and that would give the "trailer fault" message, but otherwise there should not be any power down it unless there is a problem with the reverse signal. That pin should not be hot at other times. I don't get it.
