I notice the blue wire looked to be on an awkward angle. So I pressed on this wire while programing the new number. And it worked. I was able to change the address from 1 to 57... problemed solved!... so I thought. I cycled the power. once, twice, three times... ok … well on the fourth try it revert back to ID no. 1.
This sounded like bad connection between the Program/Run switch and the board all the time. Not something that required reflashing the memory.
I have seen this problem for other issues like headlights randomly going on and off. Pins not fully inserted into their housings or connectors not fully inserted in the boards. Every wire connection can be a source for failure.

I was not sure if the run switch circuit needed continuity all the time?
Run is open circuit. The switch has to be closed to program. If there is an open circuit anywhere you will never be in program mode and the engine never accepts a new number.
