Neutral Safety Switch Question

Putting the big block 727 in I noticed that it has a single post for the Neural Safety Switch and the harness from the 904 I took out has a 3 prong connector. Can I crimp on a round connector to the single post and worry about the reverse lights later so I can crank this thing?

Second question... I wanted to see if the starter i just fought with for 2 hours was going to engage correctly and it would only dim the dome light so I'm assuming its because the NSS isnt hooked up yet..Sound about right?
