Need some help identifying this plug





My 75 is slowly going back together but can't find if this plug is used. This is part of the auto shifter wiring harness.
(In 74/75 didn't they have an even more complicated thing that also prevented it from starting until the drivers seat belt was fastened as well?)
The Neutral safety will be the purple and purple/white strip heavier gauge wire you can see in the background there
The green and pink ones are the reverse lights
