FitDVR 10-Pin Dash Camera Power Adapter for GM

The FitDVR 10-pin dash camera power adapter supplies regulated 5V and 12V power to dashcams and accessories through your vehicle’s factory rearview mirror connector for a tidy, reliable installation.

If you drive a Chevrolet, GMC, Buick or Cadillac with a factory auto-dimming or digital rearview mirror that hides a 10-pin connector, this harness converts that wiring into usable 5V USB and 12V DC outputs for dashcams, radar detectors or other in-cabin devices. The adapter is a plug-and-play wiring harness designed to preserve factory features and avoid splicing, and it includes multiple output cable types so you can connect most dashcam models without extra converters.

How will this adapter power my dashcam and other devices?

The harness accepts the vehicle’s 12V feed and provides both 12V DC and 5V USB outputs so you can run devices that require different voltages simultaneously. The included cable set covers common connector types so you can match your dashcam’s power plug without buying separate cables.

• Input: vehicle 12V through factory 10-pin rearview mirror connector.
• Outputs: 12V via 3.5mm DC and RJ11 cables; 5V via Micro-USB, USB-C, and Mini-USB.
• Multiple outputs allow a dashcam and a small USB accessory to run together.

Will installation affect my vehicle or mirror warranty?

FitDVR designed the adapter as a special wiring harness that plugs into the factory connector, so there’s no cutting or splicing of factory wires. Because it uses the OEM connector and preserves the mirror’s functions, installation typically won’t void the vehicle warranty when performed correctly.

• Plug-and-play harness fits behind the rearview mirror cover—no wire splices.
• Preserves auto-dimming and digital mirror operation by using the original connector.
• Installation is reversible; keep the vehicle’s wiring intact for dealer service.

What extra features does this FitDVR adapter include?

Beyond basic power conversion, the adapter provides an integrated LED display that shows voltage and current readings so you can monitor device draw. FitDVR also packages a full set of output cables for compatibility and offers dedicated customer support if you need wiring help or a different model.

• LED screen displays real-time voltage and current for diagnostics and peace of mind.
• Six output cables included to fit a wide range of dashcams and accessories.
• Manufacturer support available for model selection and troubleshooting.

Who is this for? This adapter is ideal for Chevrolet, GMC, Buick and Cadillac owners who want a clean, factory-friendly way to power dashcams, radar units or small USB devices without cutting wires. It’s especially useful for drivers who prefer a hidden installation that keeps the rearview mirror’s original features intact, installers who want multiple connector types included, and anyone who values an LED readout to check voltage and current quickly.
