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.

Premium audio systems are generally name brand systems (such as JBL, Bose, Rockford Fosgate, etc) that have been installed inside a vehicle when it leaves the factory. Often they more advanced systems, complex wiring, factory amplifiers, and other features that can make installing aftermarket component difficult.

I have a 1997 Ford F-350. I just bought the stereo Boss 611UAB off of here, will this wiring harness just connect to the factory wire harness already installed and then connect the wires from this harness to the wire harness that came to with the stereo?
Timmy B on Apr 1, 2016
Best Answer: Yeah if you gave them the information for your make and model the harness they send you should plug directly into the factory harness. It will probably include instructions for attaching that harness to the one for the stereo. You just wire the two together and then plug it all in.
