I replaced my 2002 stereo with a kenwood. I got a plug that didnt work but it may work with yours. I ended up having to get a connector that was different. It also had a chime module on it and was $60. It basically controls the driver side front speaker and chimes through that speaker for any warning chimes.
If you want it you can have the one that didnt work for my malibu...just pay $5.00 inc. shipping. Either way open up and see what kind of connector it has to prevent wasting ur time and $$.
Let me know.
