I'm in the process of wiring up my 68 mustang with an AAW classic update kit. I wanted to come here and see if i could get some suggestions/guidance or even critiques of my plan.

I have 20' of 2/0 cable for the battery to solenoid to starter run. The kit came with 2 175a Mega fuses and 12ft of 6ga. One fuse is meant for the run from alt to battery and the other to feed the main 10ga to fuse block.
I originally was going to bump up the alt to fuse wire with 2ga since it's a longer run. Once it got to the firewall, put bulkheads in for the alt to firewall and tie the inside fusebox feed to the 2ga on the inside.
But that would put everything on one feed back to the battery on a single 175a fuse.

My question is this: Should i run 3 lines to the front? One for starter, one for alt, and another to feed everything else up front. That way, the two trunk fuses will both get used to share the load of items.

Attached is my rudimentary attempt to sketch out a plan along with a pic of the alt wiring kit.
I may be overthinking the whole thing, which is why i came here. I like to lay out plans in my head so i can picture how it should go. And I haven't been able to settle on anything solid yet.

There are different views on this but IMO the solenoid needs to be as close to the starter as possible. I am in the camp that only runs one positive cable front to back to the battery and use the body to complete the grounding.

I could leave the solenoid up front in the stock location, but I'd much rather not have a live, unfused wire running the length of the car to feed it. I've had to clean up my share of cooked boat wiring that suffered meltdowns.
I did look everything over again this afternoon and I believe I can forego the second feed line and just run one for starter and another for primary similar to what i've done below.
