I just bought an 03 chevy and I'm putting in my pioneer cd player. I can't get the right connector at wal mart and I don't want to drive 50 miles to get a connector. Does anybody have a diagram to show how to wire the new cd player into the factory wires? Or can anybody tell me what wire needs to go to what, or the best way to do this.

i think you would have better luck driving the 50 miles to get one. it would be way easier

Also Your Truck May Need A Chime Modulator My Truck Did And What That Is. The Radio Works As The Chime Maker If You Take Out The Radio You Eliminate The Chime So The Harness Comes With A Chime Maker Their A Bit Pricey But Necessary. I Heard That The Radio Sends Signals To The Computer And May Cause Problems If Not Installed.

you can get a harness for a saturn of the same year and it will work i have done this on acouple of trucks that didn't want to spend the money you will have to find a 12v power supply but it is easy i used one of the ign fuses in the side panel you will just not have retained power the truck must be in the acc or on position i can't remember

I'd go get the adapter but here you go. Check to make sure it is the right rpo code(listed in the glove box)

oh ya i forgot to ask if you have the bose setup then you will need the right harness but if not the one i said will work
