Parts List calls CM102,Disc Stop Sensor PCB.
Exploded Views shows it is connected(wires) to CM108.
Problem is,it looks like they are mounted under the Turntable.
Pin 13 of connector CN156,is the 'Sense' pin of this Disc Stop Sensor.
It goes to Pin 2 of IC111,CXP82432-101Q.
5v to the Disc Stop Sensor(at pin 14 of CN156),Ground and the Sense Pin.
I'm not sure how this sensor counts/selects any particular disc(1-24).
