You cannot imagine the disappointment today when I swapped out light enhancer module and my right rear light still didn't work.  I then decided the problem must be in the 7 pin connector.  I took it apart and it had been pulled on too hard and was broken so I got a new one, took a picture of the old one, and replaced it.  Then I was going backwards. Nothing worked correctly.  At that point I had studied the system enough that I understood it but I couldn't figure out why I didn't have 12 volts at the right rear light so in desparation I pulled the entire harness out of the frame.  Damn mice and rats.

I still think I have a bad bulb on the left yellow amber flasher/turn signal.  It only lights up on one side of the bulb.
