Have you pulled any relays yet? I know you pulled all the fuses but what about relays?

correct, the test light is turning on once you plug the connector in or with the connector in and the ignition turned to "RUN"?
You said "With this set of wires unplugged the headlight (I assume you mean test light) still turn on when the key is put to ACC.". REALLY? Without this connected to the ignition switch that's not even possible. I think you worded this wrong.
Thank you, I will try and pull these next.The picture you posted with the head light attached to the fuse box. All the black rectangles are relay's. For sh**s and giggles will you pull all the fan relays first. Then pull all of them.
What I would now do is with the ignition switch connector unplugged, try connecting a test wire from the white wire pin to each of the other pins one at a time to see which one lights the test light.
Yes the large white is the power input and comes from the 30A fuse (now your test light). When in "On" position it gets connected to the black/white, the blue/black, and the all blue.
There is actually four wires as outputs from the ignition switch. Your black/red is power for the starter relay behind the center of the dash. Wiring at the starter SHOULDN'T be an issue as the relay shouldn't apply power until you turn the ignition switch to "CRANK" I would verify that no one has tapped in to power on this wire for the radio or some other nonsense. I am seeing something in the wiring diagram that I find extremely weird and I am gonna check more than one manual to verify. When looking at the red/black going to the starter relay I noticed a connection with a black/white wire that trails off and says "No Connection" I just find it weird that we have red/black and black/white that both light your test light....
Disconnect the connector at the alternator, pull the coil pack, pull the power transistor, check the capacitor (noise filter) disconnecthe fuel pump relay or disconnect the fuel pump.
