How to install an MP3 module in the music center

Hello. I install a Bluetooth MP3 module purchased on Ali in the music center. Two inputs are provided for its power supply - at 5V and at 12V through connectors. Do I need to disable or redo something in the circuit if only the 12V input is used.

    I recommend contacting aliexpress directly with the seller of this product and clarify this issue with him. Intervention in the circuit may lead to module failure.
