The voltage to the headlamps is hot all the time, when the drl isn't energized. Actually, there is voltage to the lamps even then, but wired a little different, the drl relay is ground for the lamps when energized. When not energized, the dark blue wire is headlamp voltage for one side. orange wire for the other. On and off, bright and dim, is controled on the ground circuit through the multifunction switch. DRL is a little different.
