[sdiy] Roland KR-375 Service information needed

[Mr&MrsAccount]

Hello All:

I just rescued a Roland KR-375 Digital Piano in fairly good condition.

I need some service information.  The Sustain Pedal assembly has had the cable unceremoniously chopped off
(well, perhaps it actually was some kind of ritual...)

It has a 5-pin DIN socket.  I don't know the pinout, or any other information about it.

I wasn't able to locate a service manual online.

Any assistance is appreciated.
