the previous owner of my car alero 03 removed the stock radio an got an after market but he chopped off the harness, now i want to change the radio and have no idea where all the wires go. i have the original harness but dont know what color goes in to what pin (in the original olds harness) can someone take a pic of theirs or tell me where the colors go from A1-A12 and B1-B12... plz

i already tried connecting the new stereo by matching wires but the cd, usb and the aux work in the stereo! i dont think is a defective radio cause it is brand new!!

plz need ur help! dont want to spend more money!

if you are completely SOL with the factory wiring, as long as the headunit is powered you could get a separate amp and it would get the signal through the RCAs
