Great harness and great price, I'm writing this review to help someone find a great harness and doesn't want to spend over $80 for a harness (harness that holds the car chimes)
Tip during installation, since the Malibu classic doesn't provide a +12V ignition/accessory cable in the factory harness an extra red wire is provided so you can go to the fuse box and tap into it. Well, i found it more convenient to tap straight into the ignition harness, I use the accessory wire of the ignition wires(brown color). I connected my aftermarket radio illumination wire (orange white line) to the solid orange color of this harness. Hope this helps someone since I went to a little of trouble myself installing the radio and now I enjoy my aftermarket radio.

I bought this to aid in the installation of a Pioneer AVH-P3200BT into my 2003 GMC Sierra. A word to the wise: Know your GMC harness before buying this (or a similar) item. Some GM products have a 24-pin connector to the radio/entertainment system and some have a lesser number. Pull the radio and count the connector pins before ordering if you don't know for sure. Don't frustrate yourself or the seller by not checking what you need up front.

That said, the harness connector was just what I needed. It was a perfect fit and allowed me to easily wire my new stereo into my truck without altering the stock harness. The Pioneer harness does need a 12v accessory line that isn't native to the GMC radio harness, but since I have a full service manual for my truck, it was easy to pick that line up from the fuse block. It's not Metra's fault that this product doesn't pick up an accessory line - there isn't one there!

Inexpensive and it makes the installation of a new stereo much easier. I like it.

I bought two of these. One for a 2002 Chevy Trailblazer and one for a 2003 Pontiac Vibe. Worked great on the Chevy, but we had problems with the Vibe. We could not get sound out of the speakers though we had full power. After doing a lot of Googling, we figured out that we had to connect the blue/white wire to one of the black wires. I believe it was to #12. If you follow the diagram that comes with the packaging and forget about trying to match up the colors, you'll be fine.
