You second 4 strap from chassis to battery is a bad idea.
You're introducing a parralel ground path for your accessories which isn't ideal.
Also, no kill switch ?

I'd suggest deleting it and running it all off of the engine block ground wire. Up this one to 1/0 or 2/0.
I didn’t mean to send you in a whirlwind of research, but I try to apply some basic principles to all my harnesses and star point grounding is one of them.
And since you referred to Haltech videos, here is one from them explaining the issues with a parallel ground path.
Np. It's good to learn. Is it still ideal to ground the accessories to the body at various points or should those be star point? Packaging that would be difficult.
What'd you have in mind for a kill switch?
The way your battery is located, it should be no big deal to run a wire to by going along the firewall then down to the bellhousing area then to the starter.
If you don't want to install a kill switch, add a wire from the starter along the engine block, then up following the cam cover.

Why go through the trouble of de-pinning everything if you're not putting heatwrap all the way to the connectors?
I like the idea of a kill switch, I just don't know how to package it yet without having to open the hood to access.
To further simplify, maybe I'll move the starter to the battery side of the 140a block.
1) Use this :
On your firewall.
Send a 2/0 cable from the battery positive to it.
Power Distribution Center. Aka OEM Jeep fuse and relay block which is still being used for some things.What is the PDC ?
This is to get power to an interior kill switch? So I'd need 2 of these studs, one to the switch, one from the switch?

Do you need a 8awg wire for those things ?
The breaker is for the SPAL fan.I don't see the need for the 60amp breaker.
Why is there a 140amp block just for the ARB ?
2 grounds are for injectors and coils. These can go to the engine.The ECM has 3 tiny grounds they don't need to go to the battery. Gm grounded them all to the block. 1 pass head 1 drive head one drive side block.
The Spal Brushless fans may need a fuse/breaker that sizeYou just don't need a 140amp block.
What spal fan needs a 60amp breaker ?!?! PDC is a fuse / relay box. Use that instead.
