Hiya. I just installed an after market stereo in a 2007 grand prix. I was wondering if anyone has an idea what wire I hook up to get the door chime back. Everything else is working fine. There must be one wire I can splice in to get the noise back...I didn't buy any connectors, I just cut and taped wires haha. If it isnt possible to get it back this way, no big deal, just curious. Thanks. If anyone has any questions for me about putting the stereo in I'd be glad to try and help.
