OK I searched until I popped a blood vessel trying to find the illumination wire color. I would like to connect my rocker switch to the illumination that powers my side mirror adjustment. The switch is going in the black space next to the power switch, however, there is a lot of wires for that switch, I am not really sure which one is the illumination wire, which I want to splice into to allow my rocker switch to illuminate when I turn on my lights. Does anyone know what color the illumination wire might be so I can splice into it? Thanks for the help in advance.
