Need a Little Wiring Help

[Penny727]

Hey, I'm trying to figure the big three connections for a 1995 YJ Wrangler. So far I have located some of the connections, but I want someone to verify I'm doing this right. I will be using all 0 Gauge Knuconceptz wire and wire run back to amps will be replaced with Knu wire.

Pictures:

Battery Negative to Engine Block:

I already found the Battery Negative to chassis and am certain that one's correct.

Here, it gets fuzzy:

Positive terminal has 2 wires:

One to a fuse box:

And one grounded???????

To the Alternator itself:

I think this is the B+ terminal and I have no clue where it goes to. Can I run a 0 gauge wire directly from this terminal to the positive battery terminal?

I was thinking it goes to the fuse box and on the fuse box panel I see a 50 amp fuse for "ALT PWR 1" and one 50 amp fuse for "ALT PWR 2". Does this mean that if I were to upgrade the Alternator, I would also have to upgrade this fusing?

Any help is much appreciated! I am certainly a noob to electronics as a whole, but I am trying to learn.
