Big 3 Upgrade: Planning Stage (Input Encouraged)

[The Architect]

I have big plans in the works for my electrical system and the big 3 is one of them and I want to do it right and well the first time so I'll take any and all worthwhile educated input. If you have your own pictures etc please feel free.

1/0 Gauge will be used.

----Alternator to Battery Positive
----Battery Negative to Chassis
----Battery Negative to Engine

I took a few nice images of the engine bay in multiple spots so you may mark and re-upload them for reference if you have suggestions for mounting locations etc.

And one direct question I have is about the metal tab/group coming off the + terminal of the battery (shown below). I want to have two tri-1/0 gauge battery terminals in the end, one on each post. Is there a way to eliminate that ugly group and incorporate it into the new battery terminal?










Onto the engine bay pictures.....ITS DIRTY...i know
