For a 2003 Pontiac Sunfire, the radio typically uses a standard aftermarket wiring harness, specifically a harness compatible with GM vehicles. This harness usually contains a combination of color-coded wires that connect the vehicle's audio system to the aftermarket radio, allowing for easy installation without cutting factory wires. It's advisable to check for compatibility with your specific radio model to ensure proper connections.
A good auto audio shop can fabricate one for you. Or, you might try Crutchfield.com

The radio on your 2000 Sunfire is probably reading "loc". If this is the problem, you need to go to a Pontiac dealer and pay them to unlock the radio. This is an anti theft device to insure your radio can not function if it is removed. The cost is from 10 to 20$
go to your local Pontiac dealer and ask if you can see the diagram
