I have a trivial problem which, however, I cannot overcome.
In what order (colors) to connect the cables in the plug and socket at the ends of the red cable (diagram below)

I struggled with it all evening yesterday: /
I have the following marking on the plug:

At both ends I connected according to the scheme "B"
When I connected the socket to the tester via a straight cable, all the LEDs were lit in turn, except for the "3" (which was not lit at all) - is that 1 pair of cables is damaged?
At the end of the cable the LEDs were lit in a different order (of course "3" did not light up either)
Later I tested by pulling more cables from the socket - then the LED responsible for this pin did not light up,
but when I pulled out one of them then the tester did not show any diodes - is it supposed to be?
