The red wire is the ignition wire, which provides power to the device when the ignition is turned on. This wire should be connected to a switched power source, such as the accessory or ignition switch.
Black Wire
The black wire is the ground wire, which provides a path for electrical current to return to the source. This wire should be connected to a metal part of the car chassis or a dedicated ground wire.
Orange/White Wire
The orange/white wire is the dimmer wire, which controls the brightness of the display based on the illumination of the car’s dashboard. Connect this wire to the illumination wire of the car, usually orange or orange/white.
Blue/White Wire
The blue/white wire is the amp remote wire, which provides a signal to turn on external amplifiers. If you’re not using an external amplifier, you can leave this wire unconnected.
