OK I just checked the motor on my car.
Part number is as Randall has found 75568A and says DR3A too.
3 wires from motor to wiring harness. Ground wire from wiring harness to
back plate via an attachment at one of the mounting bolts that hold the
whole thing to the body. No ground wire as a part of the 3 wire motor
harness.
