BlackboxMyCar Add-A-Fuse Kit

Simple Setup Guide

  • The Add-a-Fuse Kit can be used when you are installing with any hardwiring kits for your dash cam. To use the Add-a-Fuse Kit, you will need access to your vehicle's fusebox.
  • If you are using a standard hardwiring kit, then you should always connect the yellow wire to a constant fuse, red wire to an ignition switched/ACC fuse, and black to a ground. Consult our Hardwiring Fusebox guide if you would like more detailed instructions on hardwiring your dash cam directly into your vehicle.
  • For all the tools you need to properly hardwire your dash cam into your vehicle, we would recommend purchasing the Essential BlackboxMyCar Install Package.

For more detailed instructions on how to specifically use the add-a-fuse kit, check out our Add-a-Fuse Setup Guide.

Add-a-Fuse Compatibility Guide

Prior to installation, check with your hardwire installation kit to see how many fuses you will need. If your hardwiring kit has a constant + ACC, then you will need 2 fuses. If it's ACC only, then you will only need 1 fuse. By using add-a-fuses, you will turn one fuse slot in your fusebox into two for a cleaner install and added safety.

Which add-a-fuse is right for my vehicle? That answer is dependent on the vehicle that you drive. To find your answer, you can either consult your vehicle owner's manual, Google the answer, or consult the dealership where you've previously purchased the vehicle.

The options for add-a-fuses include ATO, Mini Fuse, Low-Profile and the Micro 2. All options will include their appropriate fuse. If you are unsure of which fuse option to choose, select the "1 of Each" option to ensure you have one that will work for your vehicle

How To: Install & Crimp

What's Included

Each Add-a-Fuse Kit comes with one (1) fuse, unless stated otherwise.


When tapping into a fuse using add a fuse kit, can do the amps on the fuses have to be the same?

No, they don't have to be the same.

What is Parking Mode?

Parking mode is offered on most of the dash cams available at BlackboxMyCar. While it is important to protect your vehicle while driving, it is just as important to have your vehicle protected while it is parked. When the dash cam is in parking mode, footage will only be saved when there is an impact and/or motion. Parking mode can be enabled with a hardwiring kit or a battery pack.

For more information on parking mode, click here.

What is a Hardwire Kit?

A hardwiring kit enables parking mode. It allows your dash cam to remain powered on even when the vehicle's ignition is turned off. Installation is a breeze as you will only need to find an accessory fuse, constant fuse, and a grounding point.

What is a Battery Pack?

Most customers purchase the battery pack to avoid using the vehicle’s battery to power their dash cam. The battery pack is charged by either being hardwired into an accessory fuse or by being plugged into one of the vehicle's 12-volt cigarette sockets. We recommend the hardwiring the battery pack as it charges the battery pack quicker.

How much footage will my memory card store?

On average, a 2-channel dash cam writes 16GB/hour and a 1-channel dash cam writes about 8GB/hour.

Do I need a Rear Camera?

Accidents or events don't always happen at the front of the vehicle! Having a rear camera provides coverage for any events or accidents that may happen at the rear of the vehicle.

For more information on rear view cameras, click here.

Do I need a IR Rear Camera?

An IR camera is designed to record the interior of the vehicle in low light conditions. This option is very popular among rideshare drivers.

What is a CPL filter?

A CPL filter attaches to the dash cam lens to eliminate lens flares, light reflections, and windshield glares.

Add A Fuse Kit

Arrived early, product as described.

Hi Stephen , thanks for leaving a review and for shopping with us! We are glad the product got to you early! If you have any questions, please don't hesitate to reach out

Fuse ordering confusing

So I ordered the fuse kit, got the fuse kit, opened it up, attached my dashcam, and poor me didn't verify that I had the right ones before I wired them up to my dashcam wires. Took a fuse out of my fusebox, tried to push it in, wrong fuse holder. Cut of the add a fuses, threw them in the trash, drove to 4 autozones to finally find one that had them in stock, and did it all again. Sometimes time is more important than money.


I was impressed with the quality of the product as well as the quick response, follow up I received, and how informative the staff are on varied products. I would highly recommend this company for anyone seeking electronics and/or product informaition.
