Joworthy Micro 3 Add-A-Circuit Fuse Tap Kit 8-Piece — 12V fuse taps with brass contacts & heat-resistant housings

The Joworthy 8-piece Micro 3 Add-A-Circuit kit lets you tap into a vehicle's 12V fuse box quickly and safely to add accessories without cutting factory wiring.

When you want to install dash cams, USB chargers, LED lighting, GPS units or other 12V accessories without splicing or risking vehicle wiring, this Joworthy kit provides ready-made Micro 3 (ATM) fuse tap adapters. The eight-piece set includes multiple fuse taps and replacement fuses, brass contacts and heat-resistant housings so you can connect a new circuit while preserving the original fuse protection. Everything is designed for common automotive, truck, and RV fuse boxes that accept Micro 3 fuses.

How do I install a Micro 3 fuse tap without damaging my vehicle?

Installation is a simple swap: remove the factory fuse from its slot, insert the Joworthy fuse tap into that same position, and add the new accessory fuse into the tap. No wire cutting or soldering is required, and the kit maintains the factory circuit while providing a protected new feed.

• Pop-out the original micro 3 fuse from the fuse box.
• Insert the Joworthy fuse tap into the now-empty fuse slot.
• Install the accessory’s fuse into the tap’s secondary slot and connect the accessory lead.
• Re-check fit and fuse ratings before powering the vehicle.

Will using these add-a-circuit taps protect both original and new circuits?

Yes — the design separates the original circuit and the added accessory with individual fuses so an overload on one side won’t necessarily blow the other. The dual-fuse layout helps prevent shorts or overloads from propagating into the factory wiring.

• Two-fuse layout: one protects the stock circuit, the other protects the new accessory.
• Brass contacts for reliable conductivity and reduced voltage drop.
• Heat-resistant housing to resist high-temperature environments in fuse boxes.

What devices and vehicles are these fuse taps compatible with?

The kit is intended for any 12V system that uses Micro 3/ATM fuses — common across many cars, light trucks and recreational vehicles. Typical uses include powering dash cameras, LED accent lights, phone chargers, GPS units and small amplifiers without altering factory wiring.

• Fits Micro 3 (ATM) fuse slots found in many modern vehicles.
• Ideal for low-amperage accessories like dash cams and USB chargers.
• Works in cars, trucks and RVs — check your fuse type to confirm fit.

What comes in the 8-piece kit and how durable are the parts?

The Joworthy kit contains multiple Micro 3 fuse tap adapters plus replacement fuses so you can outfit several circuits at once. Materials and construction focus on durability: brass contacts for corrosion resistance and plastic housings formulated to withstand heat and minimize warping.

• Eight-piece set includes several Micro 3 add-a-circuit adapters and spare fuses.
• Brass blades and contacts to maintain good electrical connection over time.
• Heat-resistant casing helps reduce risk of melting or deformation in hot compartments.

Who is this for: The Joworthy 8 Pcs Micro 3 Fuse Tap kit is aimed at DIY vehicle owners, auto electricians, installers and hobbyists who want a fast, non-invasive way to add 12V accessories while keeping factory circuits intact. If you prefer plug-and-play solutions, need to power small electronics in a car or RV, and want to avoid wire splicing, this kit provides an accessible, code-friendly option. Always confirm your vehicle uses Micro 3 (ATM) fuses and use appropriate fuse ratings for each circuit.
