You’ve bought your first dash cam, got it home, unboxed it, and reviewed the installation instructions. It all looks pretty straightforward and simple enough to do but, of course, you’ve already got other ideas, and you love tinkering around with technology so that it better suits your own needs. You know already that this is going to be a permanent fixture in your car and not something that you’re going to want to be regularly connecting, disconnecting, and fiddling around with on a daily basis.

So you’re considering hard-wiring it instead to your fuse box so that you can tap into the power supply of your vehicle. You’re not sure where to start, though, so luckily we are here to tell you the exact steps you need to follow to work out how to wire your dash cam to your fuse box.

First up, you are going to need to get yourself one of the readily available dash cam installation kits, as this kind of product is going to make the job of wiring the dash cam to your fuse box so much quicker and easier. It might sound like a job for a mechanic, but if you can follow basic instructions, you can wire a dash cam. The beauty of buying an advanced dash cam installation kit is that you will also get a warranty should anything go wrong. Not that we are saying that your wiring skills aren’t up to the job, but a warranty is always useful when you are purchasing technical goods, and provides that added peace of mind.

So you’ve got your dash cam and your installation kit. What next? Well first up a bit of a word of caution, not that we want to rain on your parade: do make sure that you are suitably qualified to perform the job. If you aren’t, take your dash cam and kit into a professional individual who is used to tinkering with car engines. Working on any powerful electrical system can be dangerous if you don’t know what you are doing or you aren’t confident in your abilities, so don’t leave anything to chance when it comes to electric devices and the like.

Assuming that you are perfectly capable and want to give it a go, let’s delve in and look at some of the key considerations in learning how to wire dash cam to fuse box. There are plenty of YouTube videos you can refer to, but today we’ll take you through what we recommend as the main steps to follow.

Step 1:

You are going to need to decide exactly where you want to position your dash cam. At this stage, you may want to consider who else might be driving your vehicle to take into account any height or seat adjustments that might affect the final positioning. It’s a good idea to be sitting inside your car in the driver’s seat for this stage so that you can play around with various positions and get a feel for which one works best for you.

You need to ensure that the road ahead is unobstructed, and that you’ve placed it within comfortable arm’s reach so that you can adjust the settings easily if you need to.

Step 2:

Next up you need to determine where the fuse box is located in your particular vehicle as you are going to be using this as your power source, running the cable from the dash cam to your fuse box. In most instances, the fuse box will be conveniently located underneath the dashboard on the driver’s or passenger’s side, so it should be pretty accessible. This is why it’s a suitable power source to use. Alternatively, it might be located directly below the steering column. All cars are different of course, so when in doubt check your owner’s manual.

Step 3:

Time to get a bit technical! You need to next begin the process of routing your power cable. In order to get this step correct, our recommendation is that you lay out your power cable roughly where it’s likely to be stationed as this will give you a better visual idea of how much slack you need to leave from the dash cam location, down to where your fuse box is held.

For convenience purposes and to keep everything looking neat and tidy, you might run this behind one of your interior vehicle panels. You should be able to feel your way through this step and find a convenient gap that you can tuck your power cable into, generally along the A-pillar. There will typically be a handy rubber trim that has just the right gap to sandwich in your cable. If not, it will be possible to remove the A-pillar, but again, you may decide to leave that job to the professionals.

All you need to do if you do have easy access to that A-pillar is to tuck your power cable neatly alongside any other existing cable or wires and then route it down and around the rest of your interior panel until you reach your fuse box.

Step 4:

Assuming that you want your dash cam to come on automatically the minute you turn your vehicle on, you will need to connect the installation kit when the fuse is “hot in start.” Generally speaking, vehicle fuses are always hot so that shouldn’t be a problem. If you are unsure at all though, use a regular circuit tester first to check that power is present, and then you are good to go. It will illuminate if there is power.

Step 5:

Please now ensure that your key has been removed from the ignition before you proceed any further. Then, remove the fuse in your fuse box that you identified earlier. Install in its place the fuse that comes in your dash cam installation kit and that add-in-circuit to the empty slot where you have just removed your original fuse.

Step 6:

You now need to locate a ground point in order to complete the connection successfully. Most cars should have an easily identifiable ground point that can be found and accessed. When you do locate yours, remove the bolt and add the ground lug that will have come with your installation kit.

Step 7:

You now need to ensure that all your power wires and cables are safely bundled, secured together, and discreetly, securely tucked away. We recommend you do this with something like a zip-tie.

Step 8:

Finally, you need to test that everything is in correct working order by switching on your ignition and hopefully, your dash cam will automatically power up and be ready to start recording. If so, that was a job well done and you should give yourself a big pat on the back. You can now put back any panels you’ve removed and tidy up after yourself.

That’s it! It’s pretty straightforward when you know how, and now you are well on the way to driving more safely and feeling more protected, now that you know how to wire dash cam to fuse box.
