Ok, working as intended. You do not need to do anything with the mainboard as it is not connected to the cable. At this time the world is "reduced" to the multimeter and the PS2 plug. I hope you used a piece of wire that is not isolated. Also keep in mind that only four of the six pinholes of the …
