Next, you’ll need to identify the right fuse in your car for the installation process. The fuse you choose should provide enough power for the dash cam but not overwhelm it with too much power. It’s important to double-check that the fuse isn’t already being used by another electrical device in your car.

Once you have all of the supplies ready and have identified an unused fuse in your car, you can begin the hardwiring process. Make sure to follow any instructions or diagrams that come with your power cable or other equipment. If done correctly, this will ensure that your dash cam has a reliable power source without draining your vehicle’s battery.

Disconnect The Car Battery

Now that you’ve gathered everything you need, the next step is to disconnect the car battery. This will ensure your safety while wiring and prevent any short circuits. Using caution when working around electrical components is essential, as they can be dangerous if not handled properly.

Disconnecting the car battery is simple but requires some precautionary steps. First, ensure the ignition switch is off; this will prevent any unexpected current surge when working on the electrical system. Then, remove both negative and positive cables from the battery terminals; this should be done in that order for safety reasons. After both cables are removed, check all connections in the circuit panel to ensure everything is disconnected before continuing with your installation.

Now that the car battery has been successfully disconnected, you’re ready to start hardwiring your dashcam! Take your time with this process and make sure each connection is secure by double-checking all connections before moving on to the next step. This will help you achieve a successful installation without any mishaps along the way.

Unmount The Dash Cam

Unmounting the dash cam is a crucial step in hardwiring it. To begin, locate the camera and its mount on your car’s dashboard. If the camera has an adhesive mount, use a plastic pry tool to loosen and lift it up from the surface. Once you have removed the mount from the dashboard, pull off any adhesive residue with a damp cloth.

Next, unscrew the mounting bracket that holds the camera in place. This can be done using screwdrivers or a set of pliers. While unscrewing, ensure not to damage any of the wires around it. Once you have removed the bracket and wires, carefully detach them from each other.

Now that you have unmounted your dash cam completely, you are ready to start wiring it. 

Expose The Wiring Harness

The next step is to expose the wiring harness. This typically involves taking off the plastic casing of the dash cam. Depending on the make and model, this could involve removing some screws or clips that hold it in place. After the casing is removed, you should be able to access the wiring harness from within.

Before making any connections, take a moment to familiarize yourself with each of the wires and their corresponding colors. It’s important not to mix them up when connecting them. Once you’ve identified each one, connect them one at a time to their respective points on your car’s wiring harness, ensuring each connection is snug and secure.

Connect The Wiring Harness

Now that the wiring harness has been exposed, it’s time to connect it. This step is relatively straightforward and doesn’t require any special tools. To begin, identify the power leads for the dash cam and the ground cable on the wiring harness. Then, connect each of them to their respective terminals. It may be helpful to consult a wiring diagram or manual if multiple cables are connected to the same terminals.

Once all the power and ground cables have been connected, test out the dash cam with a voltage meter to ensure everything is functioning properly. If all of the connections are secure and no current is flowing through the wrong wires, then you can proceed with mounting your dash cam.

Route The Wires

Routing the wires is an important step when hardwiring a dash cam. Once the wiring harness has been secured, the next step is to pass the wiring from the camera through the firewall. This can be done by routing it along a gap between two panels or using a grommet.

When hiding the wires, it’s important to ensure that they won’t interfere with any other components in your vehicle. This could include being careful not to run it over any sharp edges or pinch it too tightly in any areas. It’s also important to leave enough slack to access and manipulate the wires when needed easily.

Connect The Fuse Box

Connecting the wires to the fuse box is an important step. To begin, locate the fuse box in your vehicle. This can typically be found under the steering wheel or dashboard, or in the engine bay. Check your car’s manual for the exact location. Once you’ve located it, open it up and take a look inside.
