'fleet/taxi' wiring bypass diagram.

OK,

Says cut and tape on the schematic.

The 6ga wire to the ammeter stud is a blessing and a curse. Great for capacity! If the ammeter ever shorts out, you have a HUGE wire feeding that dead short with NOTHING to stop it. If you have huge amp draws inside the car, and it's fairly clear that OEM wiring doesn't matter, run a dedicated circuit to feed those loads. Using what the factory did back then seems a little old school when there are better more current approaches available.

I see you wonder why a 6ga feeding the ammeter and a 16ga from ammeter to starter relay. Think about the possible repercussions from that. None of them are good!

This upgrade is not all it's cracked up to be, it's the factory attempting a band aid fix too the horrible charging system design. There are bad things that can happen, especially with the factory ammeter in place. Many disagree with that viewpoint, yet I've never seen a disconnected ammeter ever catch on fire!

The Mad approach, even though not my preferred method, is better than the fleet one.

I won't rain on the parade from here on out.
