Is there a wiring harness connector plug that attaches to this single prong on this switch?

I don't know if that switch will work or not, although it likely will work. I do know that what is written about the functionality of that switch on the Auto Zone site is incorrect. The ECM in our cars have nothing to do with the starter engaging or not, along with the transmission being able to go into gear.

In our cars there isn't a P/N safety switch. The column switch in our cars are only for the back up lights and the P/N input to the ECM. Which is why there are only two 2-prong connectors for it. See my posts in this thread for further information (also has pictures):
