now back to the gauges, I removed the pink wire for us to focus just on the black one aka ground, notice how the big gauges just have one black wire going to them but the little guys have two, the second wire seems to loop back to the same gauge

so that is to provide ground to the little light bulb that is in each gauge to light up when you pull on the headlight switch, what I don't get is why AutoMeter didn't just include an internal bus bar that runs on the inside of the gauge from the main ground blade connector to the light like they did on the big gauges? I think that would eliminate some wire and make it look that much cleaner and neater

maybe someone can chime in and learn us something?
