I'm still trying to figure out how to hook up my radio that i got. I have a 2000 3.8 and after going to autozone and getting the harness I found that it fits into none of the connectors in the back of the radio or CD player. I have hooked up other head units in other cars but for some reason i am having a hell of a time with this. Can someone help me out? is it anything to do with the factory amp?
