    1. These pictures are very helpful! Yours is setup a bit different than mine! From what I can see, my best guess:

      YELLOW: Always on +12V
      RED: +12V out to Taxi light on top of car. ( Off when meter in use )
      BLACK: Auxiliary +12V that is only one when the meter is running. ( Dash mounted Fair light maybe? )
      CHASSIS: Ground

      Light switch, this will bypass the flag switch and keep the lights on even if the cab is not in ‘fair’ mode.

      I hope this helps, please let me know if you have any other questions!
