When replacing your factory radio with an after-market car stereo, the Scosche GM02B wire harness is a must for a quick and clean installation. It eliminates cutting your OE radio plug. After connecting it, your install is simple as the wires will color-match and easily connect to the after-market stereo. Without the Scosche GM02B, you would have to cut the OE radio plug and manually test each wire to connect to your after-market receiver.

In addition, because you do not have to cut your OE radio plug off, the GM02B allows you to reinstall your factory receiver if necessary. A great example is if you sold your car, but wanted to keep your after-market radio and re-install your factory stereo receiver. We also recommend the Scosche BOBAZT for a quick connection that is sure to last.

  • Harness is used when installing an aftermarket stereo

May 9, 2014

You can't beat Sonic Electronix when it comes to car audio! They take great care of their customers! This wiring harness along with the dash kit was absolutely FREE with the purchase of my head unit which was purchased here! At $10 each, thats an instant savings of $20!! without having to do anything! That's the reason ill keep coming back. This kit fit perfectly and worked and looked great along with my new stereo. Came with everything needed to look like a clean, professional installation. Thanks Sonic Electronix!
