So I’m about to wire up my alternator and I am a little confused. When I am connecting the ‘L’ wire, does it just go to a incandescent bulb and that’s that? I was a little confused about how that is associated with the ign wire

If the alternator has an internal voltage All the alternator really does this provide current to charge the battery.
the L lead is just used to monitor the output is alternator in volts or if it's going something crazy the idiot light will come on if you don't have a gauge.
Ignition circuit is part of your switch. as in when you turn the key it turns power on that circuit to power up the coil, the dash, whatever else.
I'd have to look at the circuit to verify exactly what it connected to, as I don't remember that off the top of my head.

Well I have a horrible discovery, I was tracing wires for the alternator and found a brown wire that looked like it had burnt. I started cutting apart the harness and it burned up. And I discovered a burn in the harness under the dash. So it looks like I get to go round two of completely disassembling the interior and taking the whole harness apart!

We are going for it and doing it right. We have stripped the entire dash and cut apart the entire harness in the cab and engine bay. We are in the process of labeling everything right now. We are going to take the opportunity to remove all the extra wires that don’t go to anything, for emissions etc. my roomate worked 2 years doing low voltage wiring and is well versed in electrical applications so we are gonna have her better than new. Every burned wire will be cut out and replaced with solder and heat shrink. And we are gonna fix all the sketchy joints in the truck.
I feel your pain, take your time and be gentle. Old wiring does not like rough handling.
One word of advise, if you are patching several wires in a bundle burnt in the same section, stagger your cuts so that the solder joints are staggered and don't bunch up. Spread them out.
Have fun

That’s good advice, we also are going to run the main charge wire in the engine bay exclusively instead of through the main harness so if something ever happens again it won’t ruin the whole harnessI feel your pain, take your time and be gentle. Old wiring does not like rough handling.

We are getting her done slowly but surely, darkness and rain has been our enemy lately. We have eliminated a lot of unused plugs and wires and cleaned up the harness significantly. Our goal is to finish it up tomorrow. I need to pick up some heavy gauge wire to run power to the fuse block from the battery and from the alternator to the battery and we should be set.

I went to Lowe’s and bought 8ga wire for the main charge wire and for the power wire to the fuse block.

I see this as an absolute win!
Like @Rice says, add a fusible link off of the alternator. I can send you a length from the NAPA spool I bought years ago if you want. It easy enough to bolt a few of them on so they're ready to go if one pops. Text me and it'll be in the mail.

I’ll shoot you a text! And are you and @Rice saying to just put one on the wire running from the alternator to the battery?
Negative
Connect the fusible link at the battery and let it be the first several inches of wire feeding power to the fuse block. Because you ran an 8 AWG wire to the fuse block I would recommend a 12 AWG fusible link. It would also be fine to install a high capacity inline fuse instead, such as the one linked below. What you are shooting for is circuit protection as close to the battery as you can get it.
