SX PX73M Missing Cables

Hello, and greetings from Canada!

I am looking for replacement cables for this very old digital piano. The sustain pedal no longer works. The back of the piano contains various outputs, pedal in, line in, line out, and midi.

Will I require more than one cable to get the sustain pedal working again? I tried contacting Panasonic and various shops for assistance, the response is the same. They all lack the necessary cables. I'm hoping I can get help here. Aside from the pedals not working, the piano is perfectly fine in all other aspects.

Thanks!
