Hi guys, not sure where to post this question but I need help re-wiring a foot pedal from Privia Px-730. My dog chewed through the pedal connection to the unit. I have since sourced a new plug as I misplaced the plug end with the severed wires. Problem is, I am now unsure which wire goes to which pin? So it's a five pin plug and the existing cable has 4 wires: Brown, Red, Grey and Yellow. Any help or wiring diagram/schematic would be greatly appreciated! -Joel
