I just bought my 2003 Alero GLS the other day and I must say I love it. The radio didnt work but thats not a big deal as im putting in a new one anyways, and i was just wondering if i could get some pointers lol.
I have the wiring schematic and it goes as follows:
2003 Oldsmobile Alero Car Stereo Radio Wiring Diagram
Radio Constant 12V+ Wire: Orange
Radio Ignition Switched 12V+ Wire: (Class 2 Data)
Radio Ground Wire: Black/White
Radio Illumination Wire: N/A
Radio Antenna Trigger Wire: Dark Green
Radio Amplifier Trigger Wire: N/A
Front Speakers Size: N/A
Front Speakers Location: N/A
Left Front Speaker Wire (+): Tan
Left Front Speaker Wire (-): Gray
Right Front Speaker Wire (+): Light Green
Right Front Speaker Wire (-): Dark Green
Rear Speakers Size: N/A
Rear Speakers Location: N/A
Left Rear Speaker Wire (+): Brown
Left Rear Speaker Wire (-): Yellow
Right Rear Speaker Wire (+): Dark Blue
Right Rear Speaker Wire (-): Light Blue
Notes: If equipped, the amplifier is located on the driver side of the trunk.
now i matched up every wire on there to the harness on the new stereo, except that i cannot find the class 2 data cable, id like to get this up and going and i dont feel like paying somebody to do it lol.
any help it greatly appreciated, thanks guys
