Setting Up with an Add-a-Fuse Kit

For a Professional-Looking Installation During a Hardwiring Kit Installation

Using Add-a-Fuse Kits

The add-a-fuse kit (also known as fuse tape or add-a-circuit) is a popular option for hardwiring a dash cam into the vehicle’s fusebox. This method offers a more professional-looking installation and is more secure in the long run than wrapping the wires around the legs of a fuse.

This article is an expansion of our general hardwiring installation guide to teach users how to install their add-a-fuse kit. Click below to view the full guide:

Add-a-Fuse Kits

Fuse Taps

For everything you need to install a dash cam, purchase our Essential Installation Kit which comes with add-a-fuses & the fuses you need.


Which Add-a-Fuse is Right For Me and My Vehicle?

Micro2 Fuse

Mini Fuse

ATO (Regular) Fuse

Low-Profile Fuse

When you are first purchasing your add-a-fuse kit, you will first need to make sure that the fuse tap you purchase is one that is compatible with your size and voltage requirements for the new equipment you are about to install and the fuse box of your car. There are 4 variations of the add-a-fuse that we carry: Micro2 Fuse, Mini Fuse, ATO Fuse and Low-Profile Mini Fuse.

To find out which fuse is right for you, you can either consult your vehicle owner's manual, Google the answer, or consult the dealership where you've previously purchased the vehicle. If you can't find the answer, then our product experts are here to help! Contact us below and we'll get back to you within 24 hours.


How Add-a-Fuses Works

Step 1: Insert Fuse Tap into Add-a-Fuse Kit

Our add-a-fuse kit will always include a fuse tap, which is meant to be put into the “Fuse 1” position, while the fuse that you select from your fusebox goes into the “Fuse 2” position (only if you are using a slot with an existing fuse). If you set them up with the wrong order, it will not feed power to the hardwire kit.

The amperage rating of the fuse you select does not need to match the amperage rating of the fuse that we include.

This video shows you how to attach a fuse tap onto your add-a-fuse, as well as using a crimping tool (ie. needle nose pliers) to attach the cables of your hardwire kit into it.

Step 2: Crimp the Add-a-Fuse Kit to Connect the Hardwiring Kit Cables Together

Using your needle nose pliers (or a similar crimping tool), trim off some of the rubber tubing (if necessary) to expose some wiring on your hardwiring cable. Connect that cable into the other end of the add-a-fuse (metal tube), then crimp them down together to make the connection. Once the crimping is done, use some force to tug on the add-a-fuse and wire so that nothing is loose. If everything feels tight, then the crimp is good and the connection is properly made.

Step 3: Put the Add-a-Fuse Back into the Fuse Slot

In total, you will need two add-a-fuses for your hardwire installation (one for a constant fuse, and another for the ignition-switched fuse) if you're installing with a traditional hardwiring kit.

Once everything is complete, the add-a-fuse simply needs to be put back into the slot that the fuse was taken out of. Please note the ground wire of your hardwiring kit does not need an add-a-fuse kit and only attaches to a metal ground bolt.

Less Strain On Car Battery (2020 Hyundai Kona Ultimate)

It has been 4 days since the installation of the Cellink NEO Battery, serviced by a fantastic installation team. The NEO gives me an ease of mind knowing that it has added an extra 13-15 hours of running time to my Dual Channel Thinkware U-1000 dash cam system whilst my vehicle is turned off (parking mode). First off, it has been less stressful for me when starting my car because I don't see the "Battery Discharged" warning anymore, knowing that the NEO has put less strain on my car battery. Additionally, with a 40 minute drive-to-charge time frame, it isn't bad at all as my commute to and from work equates to approximately 45 minutes. Therefore, I get a full charge on the NEO that gives me 20-22 hours of run-time on my dash cam. One advice I would give to potential dash-cam buyers in making the jump to buy this battery is: if you haven't gotten a dash cam yet and if you are opting for the installation service, purchase your dash cam and the NEO together and pay for just 1 installation. I made the mistake of having to pay for 2 separate installation services because I decided to buy the battery later on and could have saved $200.

Hi Kevin, thanks for leaving a review. Great advice! Hope you're loving your Cellink NEO. Come back anytime if you have any other questions.
Fits 2020 Rav4 XSE hybrid

I installed this on the small space right hand forward of the spare tire. The thickness of the Cell link Neo is just perfect. It it was a little bit thicker the rear cover will not be flush with the floor. Negative connection was done directly to the vehicle 12V accessory battery as it is mounted at the right rear tail. ACC input was connected to the accessory rear 12V outlet. Cell link Neo powers 2 Garmin dash cam minis.

I wish the Cell link Neo have an option to change the name in the app. I have another Neo battery on another vehicle and it is hard to remember the serial numbers. But overall it works great.

Hi there, thanks for leaving a detailed review. Glad to hear that the Cellink NEO is everything you're looking for :) let us know if you have any questions in the future.
Easy installation

Works as described

Hi Vinh, thanks for leaving a review!

Great service

Thanks for leaving a review, William!
Product and shipping

Shipping and blackboxmycar are great.

Product is expensive and 3m tape will not fit properly. For an expensive product from thinkware i would assume products would come with vehicle specific or general items to install properly. Other options than the 3m tape.

Keep in mind to take measurements for placing the main unit. It may not fit or able to be placed under your seat.

I have spent more money on a front stand and bolted the camera. The rear camera ive made brackets and bolted it.

Hi Blkhze, thanks for leaving a review! Sorry to hear that, but glad to see that you found a solution. If you have any future questions, please don't hesitate to reach out to us directly.
A pricey dash cam

Very pricey, yet not quite the "jump" in video quality I expected for the huge pricetag.
When the vehicle is not in motion, then video quality is very crisp and clear. However, as soon as your vehicle is in motion (driving...) the video becomes extremely "contrasted" almost like it is over-correcting for image quality, and in-turn making it worse. I had a rexing V1 (1080p) for 3 years, and saved me through 2 hit & runs... simple, good quality, cheap. I expected the jump to 4k to be huge... The video is "brighter" at best, but my Rexing V1 was definitely smoother while driving. Hopefully this is something a firmware update can fix. I have messed with the 2K @ 60fps, but the video quality drops noticeably... to worse than my 1080P Rexing V1. (Doesnt add up)
I have had my eyes on this camera since before it came out, but I am still hoping it can pull through...

Hi Kyle, thank you for leaving a review. We will definitely relay this feedback back to Thinkware. They're constantly working on new firmware for their models, especially the U1000, so we do expect it to get even better over time. That said, have you updated your dash cam to the latest firmware? If you need help, please don't hesitate to reach out to our team. We're here to help!

Awesome Product and Support

BackBoxMyCar helped me make figure out which Dash Cam system was best for my 2015 Lexus RX350. Their live chat team is great to work with and they made figuring out the best dash cam for me very easy. After having it installed I am very impressed with the reliability and capability of this product. Also it was shipped out to me in less then 3 business days, which I found really impressive. Going forward I will continue to purchase from BlackBox due to this wonderful experience.

Excellent Purchase and Service from BlackBoxMyCar

This radar module was a great addition to my Thinkware U1000 dash cam system. The setup was very straight forward and this accessory is a must for passive parking mode. BlackBoxMyCar helped me with decision to make this smart purchase through the help with one of there representatives on live chat. Their customer support team is world class and very helpful.

Fast shipping and great communication

I found this website after looking at youtube videos with vortexradar after searching for dash cameras. I have a 4 year old a119 that I have tried for hours and hours over the years to update the firmware on with no luck. It also isnt 4k and it doesn't have wifi. I find it a pain in the butt to take the memory card out and have to use the computer to download files. Now I can do it via wifi with my phone. Wifi is working fine for me with their app. I liked the a119 wedge shape and this is essentially the exact shape. The mounts are not compatible but not a big deal. This a129 pro has a much more substantial feel to it but isn't any bigger than the old model. I kind of wish I had ordered the rear camera bundle at the same time but I can always order the rear camera later. Everybody needs a dash camera to avoid the he said/she said bs that happens when there is an accident.

These guys ship fast. I am in Washington and ordered on a Monday. Camera arrived 2 days later on Wednesday. I had several texts and emails during that time keeping me updated on the progress of my order. I was so impressed that I am thinking about buying my next radar detector from them, the 360c. I am not sure if I am getting that one but that is the only one they carry.

Hi David, thanks for leaving a review. We hope you're staying safe out in Washington! We're glad to hear that you're loving your VIOFO and it's everything you need. Do reach out anytime if you have any other questions. One more thing, if you're interested in any other models of radar detectors, do reach out and ask. We may be able to source it for you at a great price. Thanks!

Hi Gerald, thanks for leaving a review!
The complete package!

I recently purchased a thinkware F800 front and rear camera combo for my M4. After researching, I heard that BMWs are sensitive to voltage drops when the camera is in parking mode.

I purchased the battery and searched youtube for a camera install video. Ironically the video I watched was a video blackbox my car made specifically for the BMW M4! Great products provided and great tutorials that helped me get it installed, thanks again Blackboxmycar!!

Thanks for leaving a review, and an image as well! We're glad to see that you had a great experience with us, Rob. If you have any questions, come back anytime!
A nice dash cam with GPS capabilities

I am very satisfied with the Viofo A119 V3 camera after using it for a week or so. It takes great video and is simple to operate. With the included GPS base I can select the speed and/or location to be recorded on the video. I just installed the optional wiring harness but have not experimented with the parking mode as of yet. Overall I am very satisfied with the build quality. The menu is easy to maneuver through and the buttons on the front are easy to use even when driving. I would definitely purchase this again!

Hi David, thanks for leaving a review! We're glad to hear that you're loving your VIOFO as much as we do.
Excellent cam

Good rear view cam with great picture. Awesome thank you!

Hi Raymond, thanks for leaving a review!
So far so good.

Good tracking notice. I’ve only had it for a short time so I’m still playing with it to get it figured out. Video is very good quality (I’ve only used it in daylight so I can speak for nighttime). Instructions are minimal but I was able to get it figured out since it is pretty simplistic (I had to search the internet to get the time zone properly set). As it stands now I would highly recommend it for anyone looking for a good and simple dash cam.

Hi Jeff, thank you for purchasing at BlackboxMyCar, and thank you for leaving a review! We're glad to hear that the VIOFO was everything you were looking for. That said, if you have questions in the future, please don't hesitate to reach out to our support team. We are always here to help!

courteous and prompt communication, item shipped promptly

I ordered dash cams and accessories from blackboxmycar and have been very happy with their services. I had to communicate with them several times regarding my order, including talking to them over the phone and emailing them. Every single time I received very courteous response and satisfactory answers. The items were shipped promptly and I had them professionally installed. Overall, I am very satisfied. Thank you.

Hi Chin, thank you for shopping at BlackboxMyCar, and for visiting our office! Glad that our team was able to help you with everything that you needed.
Easy to install, easy to use!

BlackBoxMyCar sent everything I needed to install my Viofo A119 V3. A quick YouTube search gave me the easy steps for burying the wires and finding my fuse box for my F-150. And I was off and running! Thanks a bunch!

Hi Adam, thanks for leaving a review! Glad to hear that it all worked out for you :)
