Alright, will do.

Alright, currently have one wire (S Terminal) temporarily ran to the battery. "L Terminal" pending till I find the proper resistor and a switched 12v source.

First, the Alt relay that controls the idiot light needs to be addressed. The B/W wire on the S4 chassis needs to be connected to constant power. Both of which are easy enough

Noted. .

No idea, I'll share a picture of it later.

If you find that connector you can then tap that into anything on the dash harness (stereo) that has constant power. This is the new S terminal on the S6 alt. That would do it as well.

I'll look into this
