How to Wire a Dash Cam: Easy Steps for a Clear Installation


You can install a dash cam in your car to make your driving safer and keep the track of what is happening on the road. When you have everything recorded, it gives you peace of mind. It can also help with insurance claims if there’s an accident.

This guide will show you how to wire your dashcam. You’ll learn which tools you need, how to plan the wire route and how to hide the wires neatly. It will also explain how to power both front and rear dash cams.

Tools and Materials You Need


Before you start, you should make sure that you have all the tools and supplies.


  • Hardwire Kit: This kit lets you connect the dashcam straight to the electrical system of your car.
  • Fuse Tap: This small connector will help you plug your dashcam into the fuse box safely.
  • Circuit Tester: This tool helps you find out which fuses get power when your car is on (ACC) and which one will have power all the time.
  • Trim Removal Tools: These tools will help you gently remove or lift trim pieces inside your car so you can tuck wires away neatly.
  • Zip Ties: Zip ties will help you keep the wires bundled up or attached to parts of your car so they won’t get in your way.

How to Plan Your Wiring Route


A good plan will make wiring much easier and will help you avoid problems later. Before you start running wires, you should think about where each cable will go. Proper planning will keep your car looking tidy and your wires safe.

Run Wires Along the Pillars


One of the most common ways to hide your dash cam wire is by running it up along the A-pillar (the area between your windshield and the door). You just need to tuck it in gently between the trim and the car, which will keep the cable hidden and out of your way.

Use the Headliner for Clean Setup


The headliner which is the fabric covering of your car’s ceiling is a perfect place to hide wires. You can carefully slide the wire under the edge of the headliner so it’s neat and not visible.

Avoid Obstructing Airbags


Do not run any wires near airbag zones. Airbags are usually located near the A-pillars and along the edge of the roof. You must always check the manual of your car or look for airbag markings and make sure your wiring avoids these spots.

Keep Wires Away from Moving Parts


Check that no wire is coming in the way of the steering wheel, gas pedal, seat tracks, seat belts or anything that moves. Taking the time to plan your wiring will help you avoid both messy wires and possible safety risks.

How to Wire a Dash Cam with Cigarette Lighter


Wiring your dash cam to your car’s cigarette lighter is the easiest way to get power to your dashcam.


  1. Find the 12V outlet: You should find the cigarette lighter outlet in your car. Usually, it’s near the dashboard, under the radio or by the gear shift.
  2. Plug in the Power Cable: Plug the dash cam’s power cable into the 12V socket and make sure it fits perfectly.
  3. Route the Power Cable: You can now run the cable from the socket to where you plan to install the dash cam, normally the center or side of your windshield. Tuck the wire along the edge of your dashboard and under the trim or headliner.
  4. Mount the Dash Cam: Use the suction cup or adhesive pad (provided with your dash cam) to attach the camera to the windshield. You should pick a spot where the lens can see the road clearly but is also not blocking your view.
  5. Test the Camera: You should turn your car on and make sure the dash cam powers up. Check the screen or look for the recording symbol to confirm that the camera is working.

How to Wire a Dash Cam into the Fuse Box (Hardwire Method)


If you want a clean and long-lasting setup, you should go for hardwiring of your dash cam. This will give your dash cam power even when the car is off (for parking mode).


  1. Find the Fuse Box: In most cars, the fuse box is under the dashboard on the driver’s side or inside the glove box.
  2. Find ACC and Constant Power Fuses: With your circuit tester, find out which fuses have power only when the key is on (ACC) and which ones have power all the time (for parking mode). You’ll use the ACC fuse for normal dash cam operation and the constant one if your dash cam has parking mode.
  3. Use the Fuse Tap: Take your hardwire kit and use the fuse tap to connect the camera’s power wire to the correct slot in the fuse box.
  4. Ground the Wire: Locate a bolt or screw on your car’s metal body (chassis) and attach the ground wire from your kit to this metal part.
  5. Run the Power Cable: You can route the rest of the cable along the trim and up to the dash cam. Hide the cable in the headliner, along the door trim and along the dashboard so it isn’t visible.
  6. Test Everything: Turn your car on and make sure the camera starts when you turn the key and, if you set up parking mode, test to see if it works with the ignition off.

Hardwiring your dash cam makes the installation look tidy and it’s a great option if you want both regular and parking coverage.

How to Wire a Rear Dash Cam (Front + Rear Setup)


Many dash cam kits come with a rear camera for extra safety. If you have a rear camera, it will let you record what happens behind you as well.


  1. Run the Cable: Start with the front dash cam and run the rear camera cable under the headliner or along the side trim, all the way to the back window.
  2. Mount the Rear Cam: Stick the rear camera to the inside of the rear window and install it in the center top for a good rear view.
  3. Connect the Cable: Plug the rear camera cable into the main dash cam or into the input on your rear unit.
  4. Test Both Cameras: Turn your car on and look at the dash cam’s screen or app to make sure both front and rear video feeds are clear. You should make sure the view is not blocked by the trunk, wiper or other objects.

Alternative Power Sources for Dash Cam Wiring


If you don’t want to use the cigarette lighter or fuse box, there are other ways to give power to your dash cam.

External Battery Pack


Dash cams can also take power from external battery packs. These are rechargeable batteries you can hide in your glove box or under a seat. They can power your dash cam for hours or even days which is very helpful for parking mode when you don’t want to use your car’s own battery.

OBD-II Port


Most cars have an OBD-II port under the dashboard, usually near the driver’s seat. You can get a special OBD-II power cable for dash cams. You can plug it into the port and your dash cam will work, often getting both switched and constant power for parking mode. This way is easy and will not affect the main wiring of your vehicle.

Mirror Tap


If your car has auto-dimming mirrors, you can tap into the power coming from the mirror to power your dash cam. This will help you keep the setup clean and reduce the need for extra cables.

Testing and Troubleshooting Your Dash Cam Wiring


Test Power Connections 

Turn on your car and check if your dash cam powers up. You should make sure that both the front and rear cameras work as you want them to.


Check for Interference

Make sure the wiring does not interfere with any vehicle controls such as the steering wheel or pedals. The wires should not obstruct your view or movement.


Stable Recording 

You should check the recording function of your dash cam to make sure it’s capturing footage consistently without interruptions.


Monitor for Overheating

Dash cams can sometimes overheat if the wiring is not installed properly. You should make sure the installation does not cause the camera to overheat by routing the wires away from hot surfaces.

Conclusion


It might seem difficult to install and wire a dash cam but with the right plan and some patience, you can do it yourself. Whether you want to use the cigarette lighter to quickly setup or hardwire the dash cam for a cleaner and more secure result, you can get a valuable footage that can help you in any driving situation.

It is very important to make sure your installation is safe and your wires are hidden and tidy. As long as you’re careful, your dash cam will be ready to record whenever you need it. Dash cam brands like Wolfbox give you kits that work well with most cars and make the job easier. Take your time, follow these steps and soon you’ll feel much safer every time you drive.
