The Roland GR-55 GK Input Board  = Assy 75E323P0R0 

This employs the typical Roland 13 pin DIN Female jack and
(CN501) = 14 pin 1.5mm pitch connector   - perhaps JST or Hirose?


Here are  pics of the GR-55 input jack assy.













Here is the GR-55 GK Input Board  pin out electrical wiring list:

CN501-1 = Red wire  = DIN Shell  = Chassis Ground ( Earth)
CN501-2 = White wire  = DIN pin #13  = -7V DC
CN501-3 = White wire  = DIN pin #12  = +7V DC
CN501-4 = White wire  = DIN pin #11  = S2
CN501-5 = White wire  = DIN pin #10  = S1
CN501-6 = White wire  = DIN pin #9  = GK_SW_POS_ID
CN501-7 = White wire  = DIN pin #8  = GK VOL
CN501-8 = White wire  = DIN pin #7  = GTR SIG
CN501-9 = White wire  = DIN pin #6  = String6
CN501-10 = White wire  = DIN pin #5  = String5
CN501-11 = White wire  = DIN pin #4  = String4
CN501-12 = White wire  = DIN pin #3  = String3
CN501-13 = White wire  = DIN pin #2  = String2
CN501-14 = White wire  = DIN pin #1  = String1

I don't see the images load on the web page, any chance of uploading them again? Thanks

Anyone know where I can get these 14 pin male & female connectors in the USA. Thanks Paul

We lost the photo bucket and snapagogo pic In 2018

See this thread

But crucial to use calipers and measure the pin to pin  pitch in mm

And read these threads for sources of small white J.S.T/ Hirose style metric headers and connectors used on all GK-3 type PCB boards

...got bags of them here in Oz if you get stuck, Paul...

BTW, it's 2mm pitch...
