Ford 4000 Generator/Alternator swap (Part 2)

First off, I do apologize for the confusion my last threads caused and thanks to Jmor for the help up to this point. I have attached the wiring diagram for my tractor for reference. I purchased this
kit to take place of my current 12v generator http://www.yesterdaystractors.com/Ford-4000_12-Volt-Conversion-Kit_6X10300ALTH.html. As advised by Jmor I have removed the A and F wires from both the
generator and regulator. Which leaves me with a ground at the generator and regulator and the B wires at the generator. I intend to splice the B wires together and this is where my question starts.
With the new alternator, I was given a wire harness that has a plug that goes into the alternator and has a red and black pigtail. Per the instructions, I will connect the red wire from the plug to the
battery stud on the alternator. I assume I need to run a wire from the B wires back to the alternator but where does it connect from there? I am guessing the battery stud on the alternator? Does that
mean the black is a ground? Thanks again for any help the instructions provided with the kit were not for the same style regulator as mine. Also for those wondering, I fabricated a new bracket for the
alternator so it would mount correctly.
 
If it is the common Delco 10SI it has a plug that should be marked #1 ans #2. The #2 wire goes to the charge stud on the alternator and the #1 wire goes to the ignition switch with a light bulb or diode or resister in line to stop alternator feed back. My self to save wire I hook the #1 wire to the ignition side of the coil
 
You still haven't told us whether you have a 4 cylinder 4000 or a 3 cylinder model.
So we have to follow your link or slueth out which tractor you have.
Click on the link below for the simplest diagram I have come across for wiring in a 10SI alternator.
The page is for Land Rovers but the diagram is pretty.much universal. Scroll about half way down the page.
Some good general info on Delco alternators there too.

K, from all that I have managed to gather from your past & present threads, your tractor started life wired as per diagram here. Somewhere along life's way the VR was changed to something like that drawn in at upper left. And now you are changing to a Delco 10-SI alternator as I have drawn in at upper right. This should result in one of three things, 1) I don't really know what you have, 2) it is helpful to you, 3) it just furthers the confusion.
