Cable for cvp509 yda3 to ydd circuit boards

Does anyony have, or know where I can get the wiring assembly that goes ftom the YDA3 board to the YDD board in a Yamaha CVP509 -new or salvaged? The Yamaha parts dept said that the part number of WR65360 is not actually a Yamaha part #, but the original mfg part number. Google brings up nada upon a search…can anyone help on this?
