[DelLouis]

How to connect the power cable of a dash cam: 1. The positive wire is usually red, the negative wire is usually black and grounded, and the long wire is typically yellow, connected to the car's battery or the positive terminal of the constant power supply; 2. Locate the car's ACC, install and fix the dash cam, and route the voltage reduction cable through the A-pillar to the vicinity of the ACC; 3. Open the ACC cover plate, which usually contains several small to medium-sized openings, and select the appropriate one for connection; 4. Connect the red wire of the voltage reduction cable to the ACC and the black wire to the negative terminal. The working principle of a dash cam is to digitally record and cyclically update the road conditions in front of or around the car, and it can even record data such as in-car audio, the car's acceleration, steering, and braking information.
