I need to find a complete wiring diagram for my TJ. I downloaded the Service manual, but it didn't seem to have what I needed. I bought my Jeep in August last year, and the sound bar hasn't worked since I bought it. I checked the wiring and connections ,and there is power in some of the wires at the connector, and I replaced the speakers in it as well, but no sound. Also the light in it don't work either. I'm not even sure that the sound bar is the one that came with it, and not from some other year. I also pulled the radio out which is aftermarket and it's a rats nest back behind it, so I don't know if that's where the problem is. I'd like to investigate the wiring and make sure it's all the way it's supposed to be.
