i removed said pedals and they have a 4 pint mini DIN connector.. like so:

now then, i have a PS/2 to USB connector, but the guiding clip is in a different place, so the 2 i have wont fit. does anyone have any ideas how i could connect it to USB?
if it helps (and i would love to do this, but ive not found a guide on google as to how) i have a spare USB connector and i can easily wire up the hardware to the USB if someone tells me how
cheers
