I'm sorry if my english too bad but i'm got something mystery


i've got 12 yearolds MC21 and she need to overhual engine is MC16E 1213024 and there's no GPS connector from gearbox
there's grey GPS connector from wiring loom but I can't find anything looklike GPS'swire from the case . there only pulse generator ,stator and neutral wire .
would the PGM work properly if GPS connector isn't connected? , do I need some modification to make the system really work?

I'm now try to find some bike for my trackday and I'm really novice for NSR
Very thanks for every suggestion..
