Hello, the Fit radio plug wiring description is divided into the following paragraphs:
1. The type of Fit radio plug is usually 3.5mm male head (headphone plug) or 2.5mm male head, and the corresponding plug needs to be selected according to the jack type of the radio. 2. The wiring mode of the plug is customized at the front end. Connect the white connector to AGND (the central circular connector of the end face of the plug), and connect the colored connector to the external antenna of the radio (the outermost connector of the end face of the plug).
3. After confirming that the wiring is correct, plug it in, turn on the radio, and adjust the channel to the medium wave adjustment to listen to the radio station.
Note: When wiring, the plug and interface should be kept clean and tightly connected to ensure the quality of audio transmission.
Plug in the plug behind the CD. Connect the positive power cord on the plug with the ACC control cable. Connect the black negative wire of the positive plug to the negative electrode of the battery.
