Some minor details...
Not all cars have their alternator power wire fused.
Check your circuit diagrams to confirm - you might not need that big ass fuse.
Next, it's a good idea to ground the *alternator case* back to the battery.
Positive is coming off the obvious terminal, but this is a DCV system, so what is ground reference?
Yep, the alternator case...
This is something that most people don't know.
I would add an extra ground from the alternator case (use one of the bolt / nut anchors for this for convenience) back to the battery negative (-) terminal.
