disabling APO on casio SK-1

[1964Kyle]

Hi everyone. I'm trying to put together a circuit to automatically simulate the push of a button on my casio sk1 to keep it from auto-powering off, and keeping my settings. I put together this circuit (attached) but I am unsure of how to wire it to the 5v relay and where to wire it to on the keyboard. are my attached schematics correct?
thanks,
Kyle
