I have installed my stereo the exact same way and for 10 months now I have had no problems. But by installing this way I have lost all my warning chimes because what GM has done is put a module inside the factory stereo to control these and have the audibles through the speakers. Now if anyone is really fussy about having their chimes, there is a module out there (part# GMRC01) which plugs into the factory harness, it has it's own speaker for the chimes and you can wire your aftermarket stereo to that without having to run the acc to the fuse box.
