I got a Powermaster 140 part # - 8-47140 amp alternator from summit, with internal regulator. It was said to be a stock replacement, but theres no connector for the large plug in, only the small one. And there is a large gauge wire that came with, how do I install this correctly?
 
You'll be adding a large charge cable and omitting the reconnection of the OEM charge wires at the alternator. Be sure to fuse the new charge cable appropriately.

If it doesnt have a connection for the voltage regulator, it is self-exciting and should only require the charge cable you install. You can sometimes reconnect an excite circuit so it excites with the key and not based upon RPM.

Good luck.
