Answer 2

Are you referring to the wires to connect it to the car? If so all car radios have the same standardized wire colors and almost all of them have a sticker on the radio itself with a wiring diagram. If yours doesn't try an installion manual for any common brand radio. If I had one handy I'd put it here but all I can remember offhand is black=negative, red=positive accessory, and yellow=positive battery. Speaker wires are paired as various colors with a striped partner.
