in order to see the leds in the crossover, need to connect the dim or the illumination wire input, so you dont have to use a flashlight in order to change your crossover settings at night....
my question is, what color is the illumination wire or the dim wire coming out of the stock wiring harness? oh ya, i didn't install a wiring harness to my HU. I cut the previous one and played guess and game to install my HU. So now i'm stuck, which wire is what for the dim or the illumination wire.
