Where is the power connection location for a dash cam?

There are four possible connection locations: 1. Cigarette lighter connection: This is the simplest method - directly plug into the cigarette lighter socket. After obtaining power, route the wire through areas like the glove compartment or A-pillar. This method occupies the cigarette lighter socket, and since the wiring in the glove compartment area cannot be completely hidden, there will be some exposed wiring. However, the advantage is that you can manually turn the dash cam on/off by simply unplugging the cigarette lighter or pressing its switch. 2. Direct battery connection: This requires running wires from the cabin through to the engine compartment to connect directly to the battery terminals. This method doesn't allow convenient manual power shutoff and may risk battery over-discharge. The A-pillar must be used to conceal exposed wiring. 3. ACC power connection: There's usually a secondary fuse box under the steering wheel. Locate the ACC fuse and insert a "fuse tap connector" into it (refer to your owner's manual for the correct fuse number). This method doesn't affect the vehicle's original electrical system. The dash cam powers on when the vehicle's main power is activated. The A-pillar must also be used here to hide exposed wiring. 4. Dome light connection: If your dome light has independent power (can be turned on separately when the engine is off and vehicle locked), you can draw power from it using a voltage step-down converter (power adapter). This method offers the shortest wiring distance and best concealment. The converter monitors system voltage and automatically supplies power when voltage exceeds 14V (engine running).
The power socket for a dash cam is usually the cigarette lighter socket or USB port, located near the center console armrest. I've used it several times—just plug it in, route the wire along the top of the windshield, and secure it neatly. At first, I thought it was simple, but later realized the cigarette lighter position occupies a charging port, which can be inconvenient when there are multiple passengers. However, it’s quick and hassle-free for beginners, requiring minimal tools. Remember to choose a shorter cable to avoid dangling wires—safety first. I recommend starting with this method to keep things simple. My friend’s car also uses the cigarette lighter socket directly, and it works well—neat and time-efficient.
