just remember the cars dont come with the red acc and you need to get that from the fusebox. dont connect anything to the red wire in the cobalt harness cap it off and just run a wire from the new hu harness straight to the fusebox.
as long as u dont connect anything to that red wire in the cobalt harness then ur fine

you mean run the acc wire and constant wire together so the radio is always on?
yeah, but i put the new head unit in and it seemed fine i turn up the volume no sound, i start my car none of my gauges work, no blinkers, rpms, mph, nothing worked and like the stereo was on but thats it but nothing else works whats wrong?
