Starting to go through my wiring!

Ok after studying a few wiring diagrams online to learn the wire colors - and studying the harness I have -

I figured out the electronic ignition wiring - it has a TON of splices so I need to buy some specific color wire to match the factory harness and splice the new EI (electronic ign) harness I bought in

Next is to eliminate and bypass the voltage reg. and amp gauge.. here is my idea -

Cut the alt charge wire from the stock alt a few inches from the bulkhead plug (so can be respliced back in for returning to stock)

Cut the large Ga red wire from the back of the instrument cluster - wrap in/insulate from/with harness - with that done the amp gauge should be bypassed - note not to cut the large red wire w/ fuse link on engine side harness as it is the main feed for inside car power -

Eliminating the VR is done by eliminating the green wire altogether (nolonger used with modern internal reg alt), blue wire off VR is spliced in with EI and runs inside the car to the ign switch I assume so again you eliminate that blue wire from the VR

Someone want to confirm this for me? Will the above idea work?

This seems easier to me than wrecking both harness bulkhead connectors drilling and running a frankly TINY charge wire that isn't needed with a modern alternator - I would even re-run a new 8-4Ga fused charge wire for the stocker and not use the factory charge wire at all

The Toyota alt after looking at the plug and the wiring diagram I have for that -

Has 3 wires in the plug - Green - 12v switched not hard to find in stock harness
Blue - 12v sense (to see a charge current - it's own wire to starter solenoid)
Red - charge lamp if it has one (may use this as a feed for my volt gauge)
Charge wire 4Ga straight to battery + w/ 125amp fuse
