  8. Stan, you would have to install automotive auxiliary input adapter. An automotive auxiliary input adapter will allow you to input any mp3 player or portable music player into your factory radio. This is the easiest and most cost effective way to add an audio input into your factory stereo. Here is the adapter you will need:

    Auxiliary Input Adapter for 2006 Pontiac G6

    If you’ve never installed car audio before, we advise you to take your car to an experienced mobile audio installer. As for your CD not recording, your radio may not have the capability of reading burned CD’s. You would require an after market stereo that can read CD’s that are burned on the computer. Hope this helps. Good luck with your 2006 Pontiac G6 aux input adapter installation.

  11. I have a 2009 Pontiac G8 GT. It has a factory Blaupunkt system in the car now with an amp. I’m going to add an amplifier and subs of my own, but I’m leaving everything else stock. I’m looking for a wiring diagram so I know what wires to tap into at the factory amplifier for my adjustable high to low level converter. Thanks for any help!!

  12. I have a 2002 Pontiac Grand-Am. My question is..did this car come with a stereo amplifier built in (somewhere left side of the trunk)??? The radio has no reception on AM and FM is hashy at best. The CD player is all that works fine. I want to replace it with a new car stereo. Can I buy the front adapter to mount the new stereo, and a cable harness adapter for the power, sound connections on the back, and just plug and play??? Any help is appreciated. Thanks

  13. I am looking for a wiring diagram/schematic for a 1991 Pontiac Bonneville SE to hook up my new stereo deck because my old one was stolen and all the unmarked wires clipped.. please help. Thanks!

  14. AJ King, technically you could connect your 2005 Pontiac Grand Prix amplifier turn on wire to the radio switched 12v+ wire. That way your amplifier is on whenever your 2005 Pontiac Grand Prix is on and off whenever your 2005 Pontiac Grand Prix is off. Just make sure to run an in-line fuse holder with a 1-amp fuse on the amplifier turn on wire. Hope this helps. Good Luck.

  15. I’m also looking for a wire diagram for a 05′ Grand Prix, GTP. Just one wire left and have no clue for the best place to attach it. Lead wire from aftermarket amp to where…? This is a very tough job…

  16. I am looking for a wiring diagram to find the remote wire to go to my amp i am installing on a 2007 pontiac G5. i was hoping there is one in the factory sub that is already there i can pull off of.

  17. Blackobra, as much as we would like to help you out, our resource only contains information about USDM vehicles. Good luck.

  18. Please help me find a diagram for a 2005 Pontiac Wave… I can’t find one anywhere. And to be brutal, the owner’s manual does NOT help at all. thanks!

  20. i just got a dream deal on an 84 firebird, car is mint except for stereo conns have been cut can you get me the wiring diagram for this car?

  21. Kanguro, technically you can run a wire to the ignition switch harness (orange wire) for your radio accessory wire. Just make sure you run an in-line fuse on the accessory wire to prevent damage from any shorts. Hope this helps.

  22. I need to install a Pioneer on my Pontiac Sunfire 2001, i have the harness but the car does not have the red wire(acc) to power up the radio, please help!

  23. Do you have a 2002 pontiac sunfire wiring diagram? The stereo was stolen out of the car and the people cut the plug so I have no idea what the wires go to. Thank you
