Dimming headunit
The companies that manufacture cd players try to make the displays bright enough to be seen in direct sunlight, and they dim when you turn your headlights on so that its not brighter than your guages at night thus becoming a distraction. If you don't want that to happen I know that with some cd players if you don't hook that wire up at all the unit won't dim.
