I'm trying to install a aftermarket radio. I thought I could save money by hard-wiring it all but I ripped the wires from the harness of the aveo b4 taking notes of what each wire did. I have 1 half of the harness figured out so I know where the ground cable and a few speakers go, but I don't know how to figure out the other half. So if someone could just tell me the wiring diagram with colors I could then figure out all the other colors

 

The best way is to keep the factory wiring harness & connectors intact . Order connectors of the same gender ( male or female ) as those that are made onto the stock radio .

Those connectors should have wires on them . Solder & heat shrink them to the wires leaving the new stereo .

You may have to have a little electronic box to preserve the turn signal clicking , warning chimes , etc . Not sure what you have to buy to preserve On Star ?

Thanks. I got majority of everything hard-wired. If someone can tell me the colors of the rear speakers positive and negative would help me alot. I'm down to 4 wires 2 blue and 2 yellow and I tried 4 ways of connecting the wires to my aftermarket wires but still no sound. So if anyone has pics to show which r the rear speaker wires would b great.
