Ok, So I am buying a Cobalt, 2008 Base Model, manual everything, no onstar, no pioneer...NOTHING!!!!! I just got a double Din unit for it real cheap. Well basically, I refuse to pay $100 or even close to it for an aftermarket harness so so I can keep my chimes. Seriously? So, what do i use to wire up the radio without cutting the factory wires? Not that I'm against it, I just don't like to be sloppy about it and I see no reason to even consider buying this stupid harness. Has anyone done it without it?
