Adding on 2 circuits
Start by reading this article. The fact is an alternator more than perhaps 70A is almost guaranteed to damage factory wiring............
Some don't like the way this mod is done, and I can understand that. But the article explains why "it" is a problem. If you do nothing else, pull the bulkhead connector apart and repair/ replace the bad terminals and consider bypassing the ammeter. Also examine the ammeter for damage in any case. Then run a BIG *** wire (with fuse) from alternator to battery

Simplified diagram on that page of main power distro
The main problem is where the big red and big black ammeter wires go through the bulkhead, as well as the size of wire, and the ammeter and ammeter connections.
"Back in the day" the optional 65A alternators did a pretty much bulkhead connector bypass by modifying the harness. This is commonly known as "fleet/ police/ taxi" wiring and can be seen in some of the factory service manuals. If you are unaware you can download factory service manuals free, from MyMopar
