This is the piece inside the tranny. The unconvered points gives the ground to the point at NSS on P and N

That piece engages to the tranny linkage ( despite the application legend, works te same in all cars )

If linkage is not correctly adjusted, the points won't meet between NSS and roostercomb lever hence won't source the ground to the starter relay.

Now, you can get some dirty the points inside, worn, linkage play or due worn or missed pieces like the bushing mentioned, or simply needing to be readjusted
