Update, I received the harnesses I needed to get the car running this month and got everything all buttoned up. Since getting it running I reinstalling the S6 alternator and have periodically checked the battery voltage for any severe draining like before. . There is none, everything functions as it should so the car is back in business
Thanks to everyone for your input and assistance with this. I tend to make a mountain out of a molehill at times but that's usually because I have no idea what I'm doing and need guidance on some topics so thanks again to everyone for the assistance with this.
