Red/White – 12V Ignition Switched Power

The Red/White wire provides 12V of power from the ignition switch to the radio when the key is in the “On” or “Accessory” position.

Red/Yellow – 12V Constant Power

The Red/Yellow wire provides constant power to the radio, even when the ignition switch is turned off. This feature is necessary for preserving settings such as clock time, radio station presets and equalizer settings.

Orange/White – Illumination

The Orange/White wire power is used to illuminate the radio display and buttons when the headlights are turned on.

Black – Ground
