I need help identifying some wires that were hooked up to the alternator in a …not factory way, as I’m rewiring a new 1 wire alternator in.

I just want to know what the wires do essentially and where they were supposed to go.
- from the firewall there is a loom with a red, yellow, green with yellow marks, and black.
-then the other is a thicker gauge yellow , and a green with red stripe.

The way it was hooked up prior, the yellow, red, and thick yellow, all connected together and went to the alternator and the solenoid.

Now it’s how you see it, and I just want to make it neat. It’s a one wire alternator, I have the circuit breaker mounted. Guessing the green wire will trigger it, so what the hell do I do with the other wires.

Ps. There’s also one wire from the glow plug harness that’s cut not doing anything, wondering where it goes?

This site has more info than you could ever want for your truck. I'll dig into the diagrams in a bit here for you.

If you look in the tech articles for the 3G alternator conversion those wires are explained in there. Of course if you're going one wire, none of it really matters...... kinda.

Specifically this page looks like it may have some info that helps. Wish I could help further, I ripped my entire wiring harness out and did my own.

Thanks so much, more than sufficient! Any idea on that one rogue glow plug harness connector that was terminated in my case? The color seems to be orange...

Maybe setup for manual glow plug switch at one point

On that website I linked, look at the EVTM section for some extremely in-depth wiring diagrams, that plug and wire will be on there.
