The way I see it, If you unplug the connector to the brake lamp switch, the brake lamps can't get voltage unless that circuit is shorted to voltage. The best explanation for me, is that the terminals are shorted at the connector, that way if you unplug the connector, the terminals are still shorted. There could be other explanations, but, I can't see much from here. You said, pulling the brake lamp fuse killed the brake lites, correct?
Why this just now started, I have no idea?
At the stop lamp switch, the red wire with yellow tracer carries voltage to the stop lamp switch. Hot all the time, protected by fuse 18--15 amp.
When the stop lamp switch is activated the red wire with green tracer goes hot/voltage goes to the stop lamps.
