You might be able to, if you really knew what you were doing, but I would not, especially considering the experience you may be lacking (I'm not trying to insult you in any way, it's just it isn't simple, and I doubt you want to f*ck anything up on your car) so I suggest either get it installed professionally, and see if they WILL install it using the harness you bought. If you want to do it yourself, or the installers won't install it using the harness you bought, go onto crutchfield.com, get the proper wiring harness (should be around $100-130), buy it from them OR look around for the same harness cheaper, and get it installed or follow my DIY somewhere on here and it will save you alot of trouble in the future.
I dunno what year yours is, but I believe for my cobalt, some airbag controls may be ran through the radio as well as other things, and yes, chimes are very useful when you accidentaly leave your lights on or you are about to lock your keys in your car.
