Here is my best guess as to your circuit layout:

I suspect that the pinout of D3 is as follows:
D D
pin2 ---|<|---o---|<|--- pin1 D3-A
|
pin3
D D
pin5 ---|<|---o---|<|--- pin4 D3-B
|
pin6
I confess that I don't understand the purpose of D4.

Back to home after two days outside I'll look at that, thanks for your
work, I appreciate very much.
All the bests.
