I've figured out most of the wiring on the stereo but i haven't been able to figure out the one of my car, so please let me know if you can help me

Answer
Sorry I took so long,   
  Usually your 12 volt power = yellow, Accessory Power = Red, Ground = Black, Blue = Remote amp turn-on, orange = illumination/ dimmer (Optional hook up), and for the speakers you'll have to remove the speakers and look at the wires to find those colors.
