When replacing your factory radio with an after-market car stereo, the Scosche KA02B 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 KA02B, 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 KA02B 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.

The cables/harnesses were the ones ID'd for my car.
Phillip G on Sep 6, 2014
In addition to the dashboard installation kit and wire harness, do I need to buy an antenna extension when I replace the factory-installed stereo in my 2008 Kia Optima LX with an aftermarket one?
Phillip G on Sep 10, 2014
Best Answer: I recently replaced the factory-installed stereo in my 2004 Kia Amanti and did not need an antenna extension. I cannot say for sure if that would be the case in your car but my guess is that you probably do not need one.
