I had my remote wire for my amp connected to the prong on the connector for the cd changer in the trunk. Im guessing thats what that is. bought the car with out a changer. It worked fine,turned on when the radio was on. My father borrowed the car and had to remove the system then he crossed the wires trying to hook it back up. Now there is no remote turn on only constant 12v. Is there a fuse or relay for that connection.
