Hey, i been working on my Cavalier and changing out the radio by hard-wiring it but I'm now confused. the Gray illumination wire and brown dimmer wire well they do what they say but I'm installing a BOSS 611UAB radio and the Orange is for the lights (dimmer and Illumination). I don't know what to do with the gray and brown wires and now I'm lost on what to do now If anyone knows what to do it will be very helpful.
