am i reading this right?
what i see is pin 1 being far right with no wire and the "number 1" printed on the pcb to the top right.
pin 2 with the black and red wire
pin 3 with plane black
pin 4 with the blue on the far left


what you have there is to supplies without the grounds connected to each other
red and red/black if from the +5 on the power supply
blue and black are from the separate  bridge rectifier for the display +12
