For our new upgraded version of OBD automatic memory saver, it adds the safety function of AIP; if the input power polarity is incorrect, the AIP function will automatically take effect (if the input power polarity is incorrect, the power cannot be transferred to your car); likewise, the led indicator on the memory protector will not light up. This way, your car's ECU and other electrical equipment are adequately protected during the wrong power connection..Package List:1 x OBD Memory Saver Cable1 x Clip Cable
