With the wire in the clear casing, it sounds to me that there may be an amp in that vehicle. Does the harness you purchased have a wire in it labeled power antenna? If so did you connect it to the blue/white wire of your new radio. Usually without this wire connected to turn the amp on you will get no sound from the speakers. I have seen cases that were just as you are describing.
