The orange wire is responsible for the radio’s illumination feature. This wire is typically connected to a dimming circuit and dims the radio’s display when the car’s headlights are turned on. If your radio’s display won’t dim, check to make sure the orange wire is properly connected to a dimming circuit.
Blue Wire
The blue wire is responsible for powering a power antenna, if equipped. If your car does not have a power antenna, this wire can be left unconnected.
Blue/White Wire
The blue/white wire is responsible for turning on an amplifier, if equipped. If your car does not have an amplifier, this wire can be left unconnected.
Brown Wire
The brown wire is responsible for muting the radio’s audio output, typically when the car’s phone system is in use. If you’re experiencing audio issues during phone calls, check to make sure the brown wire is properly connected to the car’s phone system.
