Dash cam wiring: fuse taps vs. hardwiring methods
Dash cams have become increasingly popular for both safety and security reasons. When installing a dash cam, you have two main options for power: fuse taps or hardwiring. Fuse taps are easier to install and allow you to plug into your vehicle's existing fuse box. Hardwiring, while more complex, provides a cleaner installation and can enable parking mode features.
For a fuse tap installation:
- Locate your vehicle's fuse box (usually under the dashboard or in the engine compartment)
- Identify a suitable fuse that's only powered when the ignition is on
- Remove the original fuse and insert it into the fuse tap along with a new fuse for the dash cam
- Connect the dash cam's power wire to the fuse tap
- Route the wire discreetly along the headliner and A-pillar to the dash cam mount
LED light bar mounting: grille vs. roof rack installations
LED light bars can significantly improve visibility for off-road driving or work applications. The two most common mounting locations are the grille and the roof rack. Grille mounting provides a sleek look and lower profile, while roof rack mounting offers better light projection and less interference with the vehicle's airflow.
