    Newbe here. Helping my oldest son put a stereo in his friends 03 Alero.
    The adapter harness connectors aren't exactly the same as the factory connector. Does anybody have a diagram of a factory connector and color codes? Thanks tmm

    That vehicle requires an interface to install a radio properly. The Axxess GMRC-01 or the Axxess GMOS-01 should be used for that vehicle.

    Here is the info for that car

    Radio 12v orange
    Radio Ground black/white
    No Radio Ignition wire (Class 2 Data)
    Radio Illumination brown
    Power Antenna dark green

    Positive Speaker wire color listed first
    LF Speaker tan and gray
    RF Speaker light green and dark green
    LR Speaker brown and yellow
    RR Speaker dk. blue and lt. blue

    Notes: If equipped, the amplifier is in the trunk, drivers side
