How to Install a Front and Rear Dash Cam (Hardwired Connection)

A hardwired front-and-rear dash cam hides the cables, runs continuously, and enables parking mode — far cleaner than a cord dangling from the 12V socket.

Tools needed

  • Nylon panel pry tool set
  • Multi-bit driver
  • Trim removal tools

Materials needed

  • Front and rear dash cam system
  • 12V-to-5V hardwire kit with fuse tap
  • Zip ties

Step-by-step

  1. 1

    Mount the front camera behind the mirror and the rear camera at the top of the back glass.

  2. 2

    Tuck the cable into the headliner and down the A-pillar, keeping clear of airbags.

  3. 3

    Route the rear cable along the weatherstripping to the tailgate.

  4. 4

    Find a switched (and a constant, for parking mode) fuse slot and install the add-a-fuse tap.

  5. 5

    Ground the kit to clean bare metal and connect the step-down converter.

  6. 6

    Tidy slack with zip ties, then confirm recording, loop, and parking mode work.

Common mistakes

  • • Routing cable across an airbag path
  • • Tapping a critical fuse like airbags or ABS
  • • Poor ground causing flicker or reboots

Maintenance & next steps

Reformat the memory card periodically and verify both channels record after software updates.

When to call a professional

For vehicles with complex CAN-bus power management or if you're unsure which fuses are safe.
