Who Dunnite GI help

[arakissun]

I must fix GI of this machine but the manual have missing exactly this page that is for connector J120,J121,J115.
Any one can you help me with information?

The GI for that game is the same for all games of the same era, so any schematics will work. What exactly isn't working? Are you looking for a GI pin-out for the J120 & J121 connectors?
