I have a 2006 impala ss, and im trying to install a double din stereo without the special wire harness needed and  verything works fine but i cant seem to find a fuse or a wire to tap into that will provide a 12v acc switch. everything i try seems to have constant power..... does anyone know were to find this in 06-09 GM vehicles? Thanks in advance.

im guessing you have your headunits power cable connected to the battery. it needs to be wired to the ignition. its usually the yellow cord. i remember on my friends old car i ran the headunits power wire to a 10v fuse for the cigarette lighter under his steering wheel ( i put a little wire breaker thing, i cant find a picture. but it had a swtich so manually stop power). it worked fine. he had a 08 montecarlo
