Need a little wiring help

[DieselRat]

I need a little help with pretty much the last piece to the wiring puzzle. I am hoping someone here is familiar with EZ-Wiring's harness. Heres what I am wanting reassurance on.

I have 2 wires from the fuse panel that are designated alternator connections.

1 is a heavier red wire (maybe 8ga) that says 'Alternator Power'
1 is white labeled EXCITOR.

I am retrofitting a GM alternator (10si) to my truck (mercedes diesel) So it obviously was never meant to be there.

This alternator has 3 connection points, I understand them as followed.
Main lug, to the battery. 1 is for the dummy light/excitor wire. The third is the sensing wire.


SOOO...The part I am stuck on is, does my 'Alternator Power' wire in the harness, go to the main lug on the alternator? Do I just cut the excitor wire, and put in either a diode or a light fixture in line, and connect to terminal '1' of the alternator? I understand the sensing wire part.

Or do I skip the harness all together and wire direct to my battery? and hook up the excitor wire the same?

I was going by this diagram I found, which makes this as simple of a job as it is, I just dont know how I should be tying my harness and the 'alternator' power into this. Seems kind of odd to run the alternator back into the fuse box, when there is no fuse designated to the alternator.



cliff notes: where does my ALT POWER wire in the harness connect in this setup. Or do I just electrical tape it up and forget about it?>!>! Thanks!
