The wire harness from the factory head unit has two illumination wires one is all orange and the other is orange and white.. now the wire harness from the after market headunit does not have a illumination wire. and when I plug in the radio nothing happens what is going on??? the wire harness also has two or three of the same wire. EX. wire harness from the stock hu two 12volt wires...two red ones...
