I just looked that up. Neat harness. I have not installed an aftermarket radio since my '94 Grand Am. And in that area, some people cut the harness in the car (which I hate). I'm used to buying a install harness that mates to the factory radio connector and matching the wires to the aftermarket radio.

Looking at this harness and it's instructions, it's still the same basic idea, it's just a little more involved due to things like retaining the door chime and other features to the car (and as a result, a few more bucks than the old stuff lol).

According to the instructions, on that harness, for the wires connecting to your aftermarket radio, you should have a Blue/White. The Blue/White wires goes from the harness to your aftermarket radio and according to the instructions, it is the "Amp Turn On Input". If you have a blue/white wire for your harness just free floating, this will be the root of your problem.

 

Sound quality not good as previous! Also have limitation at interior design. Owner should keep concentration in this points as it will help to retrieve customer satisfaction, I think so.
