Car still runs with key off ..have I wired this right?

Did a quick search but couldnt find anything specific to help me.Ive rewired my engine bay and moved the battery to the truck area. I connected the charge wire from my "one wire" alternator, directly to the +B pole on the starter motor as recommended, and it starts and runs properly...however, when I turn the key off, the motor wont shut down...Im guessing this might be a feedback problem with the alternator wire? Suggestions on how to rectify this would be greatly appreciated. I remember reading something on here or the A Body page on FB but cant find it again...

Any ideas gentlemen?
