wiring harness color code Delco 30015807

Easiest to replace would be the factory Delco AM/FM CD...plug in to existing terminals. If wires cut, you should include the plug in terminals with the replacement radio...Local Pic-A-Part is my go to salvage yard radio $25-$75...Walmart also sells radio wire install kits...$14.95? Hope this helps.

Look at the top under "Vehicle Wiring" and search for your car.
Press the tab that says "Car Stereo" and Presto, lots of good information. I hope this helps, Ray

Only place you can find a service manual is

Delco 2700 series radio Service Manual Analog Alley Manuals

If your nice to the dealer concerned they might help you with a diagram.eg what ever make car it came out in.just a suggestion.

usually a dealer issue check with the parts department.

E33 : CD Changer Communication Error
Cause: There is a vehicle/radio communication problem or internal radio communication problem.
Correction: Disconnect battery voltage to the radio and then reconnect after a few minutes. If there is still an error, determine if the problem is with the radio, the harness or the changer. Inspect for correct voltage at all connectors. If there is still an error, service the unit at an ACDelco Service Center.

go to radio shack they should have an adapter for it

I'm guessing that you wired the 2 units together including the speakers? the 2 units may be of different potentials and can't be wired together like that...they would need diodes or a relay to isolate one from another.. first you need to see if you toasted each of these by separating the wiring and trying them separately...just a thought
