Does ETC require wiring?

ETC does not require wiring as it uses its own built-in power source. The ETC electronic tag consumes power, but normally you don't need to charge the battery during daily use because there's a solar panel on the back of the battery that can recharge itself. During installation, you need to avoid the black areas on the windshield. The built-in power source typically has a battery life cycle of 3-5 years. ETC stands for Electronic Toll Collection. To apply for ETC, you need to provide the original and copies of the vehicle owner's valid ID card and vehicle license. If it's not the owner applying, you also need to bring the agent's valid ID. The copy of the vehicle license should include the page with the most recent annual inspection stamp. You'll also need a bank card for deducting highway tolls. Applicants must be between 18 and 60 years old, and the vehicle must be registered under a personal name. For company vehicles, the required documents are: An introduction letter from the vehicle owner (with official seal); Copy of the organization code certificate or business license (with official seal); Original ID card of the agent; Original vehicle license; The vehicle that needs ETC service. How ETC works: Through the onboard electronic tag installed on the vehicle's windshield, it communicates with the microwave antenna in the ETC lane at toll stations. Using computer networking technology, it settles payments with the bank in the background, allowing vehicles to pay highway or bridge tolls without stopping when passing through toll stations. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Low-carbon solution that reduces noise and exhaust emissions by eliminating stops at toll stations; Cost-saving: Reduces vehicle startup and braking frequency, decreasing wear and fuel consumption, while users enjoy toll discounts; Improved efficiency: ETC lanes can theoretically increase passing efficiency by 2-3 times, making traditional ETC updates faster and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.

I remember when I first installed the ETC, wiring was an unavoidable step. That small box called the OBU relies on the car's power supply to function; otherwise, it's just a useless piece of plastic. I connected it to the cigarette lighter socket, which was simple and convenient. But if you prefer a more discreet setup, some people wire it directly to the battery—though this is more complicated and requires professional help. When wiring, make sure the cables are securely fastened to avoid them getting loose and getting caught in the seat or door gaps, which could lead to damage while driving. After installation, test it out—when passing through toll stations, it should automatically detect the signal and charge, saving you the hassle of queuing. Although wiring can be a bit troublesome, the convenience ETC brings is significant, especially for long-distance highway trips—it makes things much easier. I recommend checking your car's power supply location before installation and choosing a suitable method that's both safe and efficient.

From actual driving experience, ETC devices absolutely require wiring for power supply. Those boxes contain built-in chips and antennas that must be connected to the car's cigarette lighter or battery system to maintain operation. Generally, connecting to the cigarette lighter is the most convenient and can be done by yourself, but pay attention to stable power supply, otherwise the device may malfunction. I've seen many friends neglect wiring issues, causing delays at toll stations and wasting time. It's recommended to regularly check the wiring to avoid aging or loosening. Overall, although wiring is a small detail, it ensures smooth ETC service and improves driving efficiency. Remember to test the sensing function after installation to ensure normal operation.

I'm also new to ETC and curious if it requires wiring. The answer is yes. There's a small motor or something inside the device that needs to be connected to the car's power to activate it. For example, the one in my car is simply plugged into the cigarette lighter. Without wiring, it has no power at all and can't function. Don't be too nervous during installation; most places provide instructions or online video guides, but it's best for beginners to ask for help. Once wired, it automatically starts working when you drive, allowing you to pass through toll stations in seconds, which is quite amazing. It doesn't hurt to learn more about it.

When discussing ETC, the wiring process should not be overlooked, as the device relies on a stable power supply. Whether using a cigarette lighter plug or directly wiring to the battery, both methods can ensure normal power supply. During installation, pay attention to insulation to avoid short circuits or leakage, which could damage the vehicle's electrical system. I also recommend choosing high-quality cables to extend the service life. Although ETC wiring increases the difficulty of installation, the convenience of quick toll payment greatly compensates for this inconvenience, making it worthwhile to put some effort into proper protection.
