Hi Pipergman, I don’t know if you still need a pedal cable. But I bought the same piano used and the previous owner broke the end off of the cable that plugs into the piano. I saw that it was a five pin din same as a midi cable so I cut a MIDI cable and figured out which wires were which and I spliced it on to the piano wire and now all three pedals work great. There’s four wires coming out of the pedal wire and one of them is ground. So once you figure out which one is ground, it’s easy to figure out which of the other three are connected to which pedal by experimenting. On my piano cable, the brown wire was the ground. And I believe red was the sustain pedal, black was the middle pedal and the remaining wire was the left soft pedal. Fortunately since the pedals are passive, it doesn’t matter if you cross the wires while you’re experimenting to find the right wire, you’re not going to short anything out.
