Question about 02 F-body. Battery in trunk and factory battery cables are good as lost.

Finally down to fluids and battery for the catfish's revival.
Grounding is complete at battery to frame, frame to motor, and harness grounds.


Problem is with my positive side. How does current ENTER the harness to power the car?
Where all does the + battery terminal connect directly? One fat cable from + terminal to starter post, check. One cable from + terminal to rear ALTERNATOR post? Another to distribution block post?

If I got that right, can any of those connections share the same cable? Using overkill 0 awg so it'll flow serious current. Should it work if I run a single 0 awg from battery + terminal, along chassis to engine bay, split the cable to 3 parallel cables: 1 to starter, 1 to ALT post, 1 to distribution post?

 

One of the + cables goes to the fuse box on the drivers side near the headlight

 

There's a standing post there with a 4 or 6 awg red wire on it. I'll run an eyelet on there and see what frys

Gonna try using the starter post as a branch point. So battery wiring will be...

Ground terminal -> chassis ground
Positive terminal -> starter post
Starter post -> alternator post
Starter post -> fuse box

Will that work? Got 2 wiring schematics for this section and they show different layouts

 

Just did.my swap. I ran three wires off battery.
1 to starter
1 to alternator
1 to post next to fuse block no issues
