I guess the thing to do now is trace the stop light bulb power back to the battery and try and find out WHY the brown wire has power in it when it shouldn't....

Bob... system is POSITIVE ground with +12v terminal of battery connected to ground. Trace cable from battery positive cable and see where it goes. Normal to have constant +12v on both terminals of bulbs when not lit. Then switch connects other side to battery -neg of battery.
