MPG wheel won't move any axis motor

MOHANLAL

Hello dear, i read all of your questions, now, my doubt is did you open the MPG HANDWHEEL, sometimes the handwheels come with 4 pins and sometimes it comes with 6 pins and you can see purple and purple/black wire is not connected if it is 4 pins. For a solution opin it and tell me.;
