What colour wire goes to which pin in the back of CD player?

The wiring for a CD player can vary based on the model and manufacturer, so it's important to consult the specific wiring diagram for your device. Generally, the color coding might follow a standard where red is for power (+), black is for ground (-), and other colors like yellow or green might be used for audio signals. Always refer to the user manual or a wiring diagram for accurate connections to avoid damage.
