I'm in the middle of moving so I can't take any pictures right now, but what I can tell you is that the ARGB plug is plugged into number 24 while the PWM is plugged into number 17 https://download.asrock.com/Manual/B450M Steel Legend.pdf (look at page 7, page 30 and page 32). I am fairly sure that everything is connected properly. I contacted the seller to see if they can deduce anything as well.
