    Wiring diagram

    If anyone has a stereo wiring diagram for a '02 Seville SLS, can you please post it here, or e-mail it to me? I am installing an aftermarket unit, and need to know what the factory wiring entails. Or, if someone can lead me to a website, where I can view this info, it would be greatly appreciated. Thanks

    Re: Wiring diagram

    Did you ever find one? If so, could you share it with me? I have a 93 Seville and need to rewire the entire aftermarket stereo that someone put it using nothing but electrical tape! They had it wired so wrong the left speakers don't work, the power antenna isn't hooked up, and all the factory harnesses are cut. I found 2 diagrams for the 93 Seville but they are both incorrect. This is what they show:

    Battery Constant 12v: Orange
    Accessory Switched 12v: Yellow
    Ground: Black
    Illumination: Gray
    Dimmer: Gray/Black
    Antenna Trigger: Pink
    Left Front Speaker Positive (+): Tan
    Left Front Speaker Negative (-): Gray
    Right Front Speaker Positive (+): Light Green
    Right Front Speaker Negative (-): Dark Green
    Left Rear Speaker Positive (+): Brown
    Left Rear Speaker Negative (-): Yellow
    Right Rear Speaker Positive (+): Dark Blue
    Right Rear Speaker Negative (-): Light Blue

    But this is NOT what mine are! The only ones I have for sure are blue ones. I did find the factory power, ground, and memory wires but nothing else. There is no pink wire, there are 3 gray wires, and several yellows, etc. Things just aren't adding up. Thanks.
