Atari Indus GT Help

Trying to revive an Indus and hope someone can give me a hand.

This drive has a Chinon mechanism in it.  However the three plugs that connect to the main PCB are unplugged.  I can't find which plug goes where and was hoping someone could post a pic.  I've got the Tandon mech figured out but can't find any info on the Chinon.

Thanks for any help!
