I have a 98 for mustang and I wired a new radio. When we bought the car there was already and aftermarket radio so I used that harness. I wired all the wires up and made sure they were tight when I plugged in there was power to the radio but no sound when I tried to play a song. After pulling the stereo aging I looked at th harness and on the harness that has all the speaker wires the wires seemed to be just sliding in and out so I think te harness is bad is that it?
