2000 Pontiac Sunfire OEM Radio Wiring

I've begun the install on this yesterday but couldn't finish in time. Now my girlfriend is pissed. I'm off today so I've been trying to finish it, however I cannot find an OEM wiring diagram for the color coding of the factory wires so I can match them up with my JVC CD player. We just purchased a JVC KD-S31 MP3/CD/WMA player and the faceplate kit to fit for it. That's all put together and ready, wires on both the new harness and the factory harness are twisted up(I cut the plug off the factory and I'ma wire it to the new cd player's wiring harness which lists everything making that at least east) waitin to be taped, the electrical tape's sittin in the seat, but I'm not messin with that til someone can put me onto some type of help. This morning, the whole instrument panel lit up, AB/Air bags/check eng./etc . Though I just left the wires comin out the console, I'd imagine the ground hit another wire cause the inside dome lights/acc. lights don't work currently anymore since I yanked the factory radio out. But this is what I need, can someone put me onto the OEM color codes or a stereo wiring diagram for the '00 Sunfire? There's a site that everyone refers to but I can't recall the address off the top, but those colors don't match up to the wires IN our Sunfire. Please help me out y'all, I'm tryin to have this in before nightfall. Feel free to PM/email me if you have timne. I've been reading the forum for 4 hours back trying to find the answer to my questions but I had to sign up due to not finding what I was lookin for. Keep it easy yall.

And we got the plug/wires for the CD deck, which I've already said, but I know its smarter to go out and buy a harness that plugs in and eliminate the gruff, but its one of those check-to-check months and I've finally gotten the chance to get the faceplate kit for the stereo and I've decided to put it in now while I got a chance. I'm going out in a sec to write down the factory colors I HAVE on the wires, then run down the JVC's coding. InstallDR and 12volt's charts don't match up as I've written them down, went out to finish the install and got stumped as the colors do not match up. Hope to hear from some of you guys. I'm gonna check back frequently so I'll be able to answer any of your questions.

You made a small boo, boo. Hopefully, it will not be an expensive lesson, but I am sure you are wiser as a result of it. The factory stereo that you have runs on a CLASS 2 system. You can't just cut the wire and join things up like the old stereo in your other car. You need one of these harness to retain the diagnostic funcions of the OEM radio. Wire everything that you cut up back and put the OEM radio plug back into the radio and everything should go back to normal. I hope. Post your results and see what else we can help you with.   Be careful whose advice you buy, but be patient with those who supply it.

Alright, well, I made an error on that I guess cutting the harness' plug off. I've installed a bunch of radios/amps the same way with no problem, guess I should have done my homework a little more on the TLS on the Sunfire. Plugging the radio back into the car is not an option though, unfortunately. There's no sense for me to put the unit back IN to the vehicle when there is an issue with the CD deck. Which is why we're attempting to put the JVC in it now. CD's won't play period on the factory, so its gotta be replaced with something that will. As for putting the factory in the trunk so it doesn't fudge up the TLS, someone drop some knowledge on that for me, thanks.

I have to agree with pencil you have to put you factory harness back on  no matter what you want to do because the bypass hooks up to that harness and then is ran to the trunk where you put your factory radio. if you don't do this you will have major problems with your car. if you can't afford the harness now wire the harness back in put factory in then get the harness and put it in. Don't forget your girlfriend is already pissed don't let here find out you might have f'd up her car or you will never hear the end of it.
