Product Description

Littelfuse ATO Add a circuit kit allows easy installation of additional circuits without cutting or spicing. Turn one fuse slot into two while providing protection for both circuits. Maintains new car warranty. Use with ATO fuses up to 10 amps. Includes ATO 3, 5, 7.5 and 10 amp fuses. From the manufacture: adding a circuit, always use a circuit protection device with a fuseholder or fuse block whenever adding additional circuits to ensure optimal safety. The fastest, easiest option for installers who need to add a circuit for application such as electronic components, is Littelfuse's Add A Circuit Fuseholder. Add a circuit is available in ATO and MINI blade fuse versions, is designed to facilitate installation of fuses for accessories of 10 amps or less. The Add-A-Circuit adapts the fuse block to the installers needs, quickly turning one slot in the fuse block into two. This provides a safe, economical alternative to splicing or fuse taps.

Great product. Good quality. Came with several fuses (10, 5 and others). Came with instructions, so I knew where to connect the original fuse this guy was replacing (well, adding another circuit to, to be more precise).

I used to it wire LED strips that I installed on my car. Connected 'em to a fuse that gets power only when the engine is running, so I get good looking bright DRLs that look nice at night too.

Shipping was fast and packaging frustration-free.

Definitely recommended.

I bought this to hook up an extra cigarette charger for my car's phone cradle. Unfortunately I didn't open my fuse box prior to purchasing and when I went to install, I found out it wouldn't work for me. Because this sits a little higher than a standard fuse, there are no spaces in my box that allow for it to fit (2001 Audi A4). Additionally, my car doesn't have any standard fuses under 15A and this device requires that it be under 10A each. They do make mini-ATM model for the smaller fuse types - turns out, this is what I need...

Solid product to reduce wiring hassles though.

It doesn't get much easier than this. Pull out an existing fuse and plug this little guy in and you get an additional circuit while maintaining the original one. Way better than splicing into power lines in your vehicle's harness.

I was hard wiring a radar detector in my car and thought I was going to have to splice a wire. This product was recommended to me and it worked out wonderfully.

The concept is brilliant, but the installation is challenging depending upon how much room you have in and near your fusebox. I wired two additional cigarette lighter sockets to my car (for a radar detector and rear backup camera). It cost me $30 in parts and would have cost me $100 for a professional installation. If I had unfettered access to the fusebox with the knowledge I now have, it would take me 5 minutes each installation. However, the actual installation took me 90 minutes to 2 hours (for both lighter sockets) given my inexperience and small, cramped work space.

I am a beginner-DIYer and tried to add a couple of circuits to my car. So I ordered this kit, not knowing that there are certain differences in sizes of car fuses.

It turned out that newer cars now use mini-fuses (ATM), but this one is a regular-size fuse (ATO).

Amazon also sells a similar ATM-sized kit (also called "mini fuse"), so please check the fuse size before ordering, especially if you have a newer car and/or a foreign made car.

This one MAY NOT FIT your car!

I can't say anything bad about this particular kit, so why 3 stars?

The Add-a-Circuit kit is a great idea to neaten up any interior work you do: without it you typically have to jam the device you want to wire into the fuse slot on one side, and force it to fit with the fuse in the socket. That works just fine, but this makes it a bit easier because the Littelfuse Add-a-Circuit plugs right into the fuse box and provides you a capped wire you can use to hand-splice in your device without having to fool with the fuse box socket.

It's important to note though that newer vehicles have a different sized fuse! You should check your fuse box not only to make sure you have these older fuses and not the 'mini', but also to see if this would still fit inside the fuse box and not get in the way of other fuses or the cover.

The picture posted is not correct.

I would say this pig-tailed fuse is ingenious. By tapping power from the fuse panel inside the car save tonnes of time from having to fish power wires from the battery into the inside of the car.
