I ended up deciding to go with orange for the primary color. I tried the covered white LED, but it didn't do it for me. White on its own looked fine, but seemed to have a lot of oversplash and lighting up the whole thing. The orange leds I ended up with do the same, but the warmer color is much easier on the eyes; as well as that bit dimmer to make a difference.
I also managed to get into the HVAC to replace that bulb; and fixed a rattle in the process. Whoever was in there for the radio put it back together without all the screws...
sigh
Somehow lost the ring cover for the ignition switch, no idea how.
My gear indicator uses super tiny bulbs, and the junkyard one has the more standard sized ones. So, I left that alone for now.
I plan to replace the shifter light when I try to figure out the stupid shift lock thing.
As for the alarm computer, I figured that out remarkably easily. I checked the wiring diagrams and discovered that the starter wire out of the ignition switch is black/white. So while tracing the anti-theft harness I found an odd little pigtail connector that had a black/white wire jumping two pins. 🤔
So I traced back farther and found the anti-theft harness plugged into a connector that had black/white wires going to it. Got it all unplugged, and found the little loop pigtail was the same female connector as what I unplugged from the car's wiring. Chucked it where the anti-theft harness went and the car started. I made a way bigger deal of it than it ended up being, lol. idk if this is factory, or something that was modified as part of the security system install, but it made things easy.
I did note when glancing at the wiring diagrams that there is a headlights auto-shutoff feature, which my car does not seem to do. Something to investigate later. I quite like the auto-shutoff, as my other two Toyotas have that. To be honest, I think modern cars take "auto" headlights too far. They don't automatically shut off unless the switch is set to "auto." Cars did this better in the 80s and 90s lmao
