Anything is possible. I made an adapter to convert the radio plug in my wife's Hyundai Elantra to the same plug on my 04 Blazer, so I can hot swap radios if I ever want to, plus getting aftermarket radio adapters is a lot easier for the Blazer's generic GM plug than the Elantra...

With the newer style, you really only need the larger plug. I believe the smaller one is for systems with Bose audio, which incorporates a stand alone amp and all, so I wouldn't even try to get into that...

But all you would need is the pinouts and a couple plugs to just make a adapter harness. I certainly wouldn't go hacking up the wiring in the dash just to change the plug...

Do you know where can I find male connector for the old style harness? So, I will be able to use the old harness and the new one without touching the original factory wires.

It's important to note that the newer style radio you show are VIN coded to the BCM. They have to be program matched to the BCM by a GM Tech tool. You can't just plug one in and have it work. I'm not 100% positive, but I doubt the older style BCM can be programmed to use the newer style radio if that's what you're trying to do.

I think your project might be a lot more involved and difficult than just changing over the wiring harness and plugging in the new radio.

No, I already find a method to match the VIN coded using eeprom programmer
