Does ETC installation require wiring?

ETC does not require wiring as it uses its own built-in power source. ETC devices come in solar-powered and non-solar-powered versions, but both rely on batteries within the device. Solar-powered ETCs do not need regular battery charging during use because they feature a solar panel on the back that automatically charges the battery. During installation, it is important to avoid the blackened areas on the windshield. The built-in power source typically has a battery lifespan of 3-5 years. ETC stands for Electronic Toll Collection, which is an electronic toll collection system. To apply for ETC, you need to provide the original and photocopies of the vehicle owner's valid ID card and vehicle registration certificate. If the application is made by someone other than the owner, the agent's valid ID card is also required. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. Additionally, a bank card for deducting highway tolls is required, and the applicant must be between 18 and 60 years old and own the vehicle in their name. How ETC works: The onboard electronic tag installed on the vehicle's windshield communicates with the microwave antenna in the ETC lane at toll stations. Using computer networking technology, the system settles payments with the bank in the background, allowing vehicles to pass through highway or bridge toll stations without stopping to pay tolls. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Reduces noise and exhaust emissions by allowing vehicles to pass through toll stations without stopping; Cost-saving: Reduces wear and fuel consumption by minimizing vehicle starts and stops; Improved efficiency: ETC lanes can theoretically increase traffic efficiency by 2-3 times, making traditional ETC faster, more advanced, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.
When installing ETC, wiring is indeed required as the device needs to be connected to the cigarette lighter or directly to the battery for power. Last time I did it myself, I purchased a dedicated cable and routed it along the roof trim panel to ensure it doesn’t obstruct the view. The whole process took about half an hour, but you must be careful not to leave the wires exposed, as this could cause a short circuit or affect battery life. Nowadays, ETC installation points offer free services—they’re more professional and can handle wiring details properly to avoid vehicle damage. I recommend new car owners not skip this step. While ETC brings convenience on highways, neat wiring ensures safety and reliability. Developing a habit of regularly checking the cables can extend their lifespan.
Installing an ETC really requires wiring. I just installed mine a month ago. The device is stuck on the windshield, but the wire has to be routed from the cigarette lighter. My friend helped by tucking it along the door frame to prevent it from dangling. Wiring is actually quite simple, but it's important to choose good quality cables; otherwise, they might loosen and lose power after a few months. Some cars connect directly to the battery, but I've heard it can cause battery drain, so it's better to use the cigarette lighter port. DIY installation saves money, but beginners can go to a 4S shop—they're more skilled. ETC saves time on the road, and patience is key when wiring.
