I did this video when I installed my alternator because I knew I would forget what or how I did it. Not sure if it will help, but have a look see. May have to skip forward to the wiring.
I also took the wires on the external regulator and just piled them together. This allowed for everything to be in place in case I opted to use them again later. I never did.
