【Installation Method】 Use a multimeter-do not guess by wire color alone-to find the +12V and ground terminals on your car's connector. Insert the adapter's red wire into the +12 V slot and the black wire into ground, ensuring metal-to-metal contact. Start the vehicle and verify ~12V with your meter. Then plug in the USB buck module; its LED indicates normal operation. Secure the harness with tape. A brief misconnection won't damage the module. 【Universal Dashcam Power Adapter]】 Fits any live 12 V source in your vehicle-auto-dimming mirror, reading lights, lane-assist or rain-sensor harness.
