Did you check for voltage to and from the brake switch, use voltage tester. Orange wire is hot all the time, white goes hot when brake switch is activated. Your lower brake lites are wired through the turn switch, the highmount, isn't. Does the high-mount brake lite work?

Do you have power going in and out of the brake switch? If so test the turn and hazard switch
