I believe this is the simple addition to the wiring kit that you'd need to run a two-prong alternator. I have no idea why this isn't included on a kit that was purchased for trucks that come with a two prong.

Question is, should I get the kit or should I just get an internal regulated alternator as noted above? Not sure of the pros and cons of either style alternator. I need a new one, so it doesn't really matter either way to me.
