I just recently bought a used tiburon from a dealership it didn't come with a radio. Also whoever owned it before cut the plug piece and there were just the wires. So I looked up the diagram and hooked up the radio I bought and noticed that there were two wires left over one light brown and one gray. The wires go to the harness that goes back into the car not the one that plugs into the radio. What do the wires go to. I didn't see them on the wire diagram. My radio works good and sounds great but I just want to know what those wires go to.
