have a pioneer deck id like to put in but not sure whether or not the stock radio has a harness or not without tearing it apart
yes it just plugs into the back of the radio but it wont just plug into to replacement radio, you will need to buy another harness that you plug the factory into then it connects to the new radio or. you could just tap into the old radio wires (don't need a harness) and hard wire it in Radio 12v red/white + radio harness Radio Ground black/white - radio harness Radio Ignition (GMLAN Serial Data) Radio Illumination N/A Factory Amp Turn-on pink + radio harness Power Antenna yellow + radio harness LF Speaker +/- tan - gray +,- radio harness or amp under driv dash RF Speaker +/- lt. green - dk. green +,- radio harness or amp under driv dash LR Speaker +/- brown - yellow +,- radio harness or amp under driv dash RR Speaker +/- dk. blue - lt. blue +,- radio harness or amp under driv dash for this Radio Ignition (GMLAN Serial Data) go to the fuse box and use the fuse for the sunroof (even if you don't have one the fuse is still there)
