Just happen on this post late, not that I go on this part of the forum much, but my bet currently without checking much is the alternator regulator area.
Unplug the dark blue wire with the tracer from the alternator. Check the wire for voltage. It should not have voltage with the key off. If it has voltage look in the direction of the ignition switch. If it does not have voltage, leave unplugged and go to next step.
Check the other field wire at the alternator for voltage also check the resistor for voltage. If there is voltage remove wire (alt/reg side) from resistor check the wire for voltage, if there is still voltage remove the alternator and have it tested.

Unhook neg bat cable, shuts off.
Normally speaking the car would still run if you were to remove the battery cable as the alternator would still supply voltage to the electrical system. It did not in this instance, further pointing the finger at the alternator area.
Of course this is all assuming the harness was correctly installed.
