*Friendly reminder: If you want to use the hardwire kit, since it involves the fuse box, we recommend having it installed at a professional service center. Incorrect installation may damage the fuses. Important:Red: ACC Power, YELLOW:Constant Power, BLACK: Attach to the Grounding.Note: Connecting the red wire to constant power by mistake may drain your car battery! Please note: Connect the black ground wire first, then connect the yellow and red wires last. You need to start the car first, then turn on the time-lapse recording function in the dash cam settings. After the car is turned off, the time-lapse recording mode will start working. Thank you.
