James,
No Kim did not include the little plastic cover for the trans section of the harness, not sure if that would be something she would have. I would get the correct harness instead of trying to track down all the little pieces. The wire that controls the reverse indicator light is tied into and comes with the correct trans harness. I got mine from Evans Wiring, call and tell them what you need and he will fix you up.

M&H also makes the proper harness and you can get them through Year One.
If you ever need any correct wire terminals or plug covers remember our cars use Packard #56 connectors. Do a Google search and all kinds of plugs and terminals are still widely available.
