12SI Alternator Install - Check my math!

[saxart]

I got the 12SI wired up today and was hoping someone could check my math. I know there are a number of ways to wire this, but I chose to do it like this guy did:

First I pig-tailed the BLUE and BROWN wires together:


Then I ran the #2 terminal on the alternator down to the post on the back, along with my original RED wire, and put the blue wire (which is an extension of BROWN) to the #1 post on the alternator:


What I'm left with now is a WHITE and BLACK wire:


I see in the post referenced above that the white wire isn't used any longer. Do I need to put the ground wire anywhere, or can that go bye-bye as well? I know there are other ways to do this mod, but I just want to make sure that what I have will work. Please let me know if you see anything that looks "wrong".

Thanks
