My hubby really wants to put his stereo system in our van. Went to Best Buy tonight to look for the wiring harness and was told it would cost over $100! I found another wiring harness on ebay and a couple of other sites for $10-$40, but they say it wont work with On Star. Our van has the On Star option, however we do not subscribe to it. So my question, which wiring harness would we need??
 
i would go with a professional and pay what they want to install it if you use the wrong wire or wiring you can short out the vehicle and make it worst. going the cheap way is not always the best way.
