Yellow Wire (Constant 12V+)
The yellow wire is the constant 12V+ wire, which supplies power to the stereo system even when the car is turned off. This wire is usually connected directly to the car’s battery or fuse box. It is essential to make sure that this wire is connected properly to avoid any electrical problems.
If the yellow wire is not connected correctly, your stereo system may not work at all or may not be able to retain any saved settings or presets.
Red Wire (Accessory 12V+)
The red wire is the accessory 12V+ wire, which provides power to the stereo system when the car’s ignition is turned on. This wire is usually connected to an ignition-switched power source or fuse box.
If the red wire is not connected correctly, your stereo system may not turn on at all or may only turn on when the car’s ignition switch is in the ‘accessory’ or ‘on’ position.
Orange Wire (Illumination)
The orange wire is the illumination wire, which controls the stereo system’s display brightness. This wire is usually connected to the car’s dimmer switch or the headlight switch.
If the orange wire is not connected correctly, your stereo system’s display may not function correctly, or the display may be too bright or too dim.
Black Wire (Ground)
The black wire is the ground wire, which provides a path for electrical current to return to the car’s battery. This wire is usually connected to a metal part of the car, such as the car’s chassis or a nearby bolt or screw.
If the black wire is not connected correctly or is loose, your stereo system may not work at all or may produce a lot of electrical noise or interference.
