Got it back in the cluster and doing some bench testing. Here I am at about 13.5 volts, with some dazzling LED strip lights! I have had green LEDs in the factory bulb location for years and they definitely help, but the gauges are still super hard to see with any ambient light (i.e. street lights). We'll see how this works out, it can't be any worse.
Shout out to
@moparmat2000 for his threads on putting the strip lights in the cluster and giving me the idea.
