I need help wiring a 2003 Grand Prix LTD?

I just bought a new JVC CD player well my dad and I are trying to hook it all up, we went to auto zone and got all the parts we need, wiring harness and faceplate kit. We got all the wires stripped and hooked to the right ones except when we plug it in there is no sound CD player works just no sound. There is an extra little clip that has 4 extra wires that need to be hooked up and we KNOW that's what the problem is. If anyone knows where these wires belong please let me know or if you know where i can get a FREE wiring diagram that would be great!! Thank you!!

Answer:

If one of the 4 wires is pink, connect it to the blue/white wire from the JVC head unit and see if that helps. (The blue wire in the main harness should also be connected to the blue/white JVC wire).

Is there alot of smoke or is it relatively dark? that would desire to point that the aggregate point isn't appropriate: you're the two working too wealthy or lean based on the colour and that would have a huge result on gasoline economic device. if so there's a situation with the gasoline transport device, the injector according to possibility or the chip. time-honored tuneups fairly advance gasoline economic device. ultimately it would desire to be the transmission, if it fairly is not shifted on the splendid time you're able to desire to be working at bigger rpms and burning greater gasoline. you could try that situation your self by observing at what rpm the engine shifts and referencing the information interior the owner's handbook. besides the shown fact that it relatively sounds like it fairly is something to do with the computing device this is fairly costly too. it relatively is recommended to evaluate a various mechanic.
