Does the ETC device require wiring?

[SanLukas]

There are two power supply methods for ETC devices. One is the solar-powered ETC electronic tag, which can automatically charge without wiring. The other is the ETC electronic tag that requires additional power supply (such as cigarette lighter power supply or battery power supply). The cigarette lighter power supply requires wiring, while the battery power supply does not require wiring. The battery has a validity period of 3 years, and a new battery can be replaced after 3 years. The wiring method for cigarette lighter power supply: 1. Take out the ETC device and stick it to the upper middle part of the front windshield with 3M adhesive; 2. Reserve 5 to 10 cm of the ETC device's power supply connection cable, and insert the cable into the gap of the top trim panel; 3. At the turning point, a plastic pry bar can be used to insert the connection cable, extending along the sealing strip all the way to the passenger foot space; 4. Lift the passenger foot mat and hide the connection cable under the mat; 5. Plug the connection cable into the cigarette lighter to obtain power, and the ETC installation is completed.
