Which stock harness wire can I safely tap into for the dimmer signal on my aftermarket stereo?  It's a PITA to change the color settings all the time, and the daytime setting is distractingly bright at night posing a safety hazard.  Thanks.
 
on my 97 sunfire it was an orange wire.   I believe the12volt.com has a wiring schematic for sunfires and cavaliers..  Check there.
