1. Product Overview
The Qizpcer Add-a-Circuit Fuse Tap Adapter provides a convenient method to add an additional circuit to an existing fuse box without cutting or splicing wires. This kit includes adapters for Standard, Mini, and Low Profile Mini blade fuses, making it compatible with a wide range of vehicles and applications. Each adapter features a dual-slot fuse holder, allowing the original circuit to remain protected while providing a separate fused connection for a new accessory.


2. Safety Information
Always prioritize safety when working with vehicle electrical systems. Failure to do so can result in electrical shock, fire, or damage to the vehicle.
- Disconnect Power: Before installing or removing any fuse tap, ensure the vehicle's ignition is off and, if possible, disconnect the negative terminal of the battery.
- Use Correct Fuse Rating: Never exceed the recommended amperage for the circuit you are tapping into. Use fuses with the correct amperage rating for both the original circuit and the new accessory.
- Identify Correct Fuse Type: Ensure you are using the correct size fuse tap (Standard, Mini, Low Profile Mini) for your vehicle's fuse box.
- Professional Installation: If you are unsure about any step, consult a qualified automotive technician.
- Insulate Connections: Ensure all electrical connections are properly insulated to prevent short circuits.
3. Setup and Installation
Follow these steps to properly install the Add-a-Circuit Fuse Tap Adapter:
- Locate the Fuse Box: Identify your vehicle's fuse box. Common locations include under the dashboard, in the engine bay, or in the trunk. Refer to your vehicle's owner's manual for the exact location.
- Identify a Suitable Fuse Slot: Choose an existing fuse slot that provides power only when desired (e.g., ignition-switched for a dash cam, or constant power for a charger). Ensure the chosen circuit has sufficient capacity for the new accessory.
- Select the Correct Fuse Tap: Match the physical size of the fuse tap (Standard, Mini, or Low Profile Mini) to the fuse slot you intend to use.
- Insert Fuses into the Adapter:
- Insert the original fuse (removed from the vehicle's fuse box) into the lower slot of the fuse tap. This slot protects the original circuit.
- Insert a new fuse (with the appropriate amperage for your new accessory) into the upper slot of the fuse tap. This slot protects the new accessory.

Connect the positive wire of your new accessory to this connector. Ensure a secure and insulated connection.
- Insert the Fuse Tap: Carefully insert the entire fuse tap adapter into the chosen fuse slot in your vehicle's fuse box. Ensure it is fully seated.
- Test the Circuit: Reconnect the battery (if disconnected) and turn on the vehicle's ignition. Test the new accessory to ensure it functions correctly.



4. Operating Instructions
Once installed, the Add-a-Circuit Fuse Tap Adapter operates automatically. The new accessory will receive power according to the circuit it is tapped into (e.g., constant power, ignition-switched power). The two fuses within the adapter provide independent protection for both the original circuit and the newly added accessory.
5. Maintenance
The Qizpcer Add-a-Circuit Fuse Tap Adapters require minimal maintenance. Periodically inspect the connections for any signs of corrosion or loose wiring. If a fuse blows, replace it with a new fuse of the exact same amperage rating. Do not use a higher-rated fuse, as this can lead to electrical damage or fire.
6. Troubleshooting
- New Accessory Not Working:
- Check the fuse in the upper slot of the fuse tap. If blown, replace it.
- Ensure the fuse tap is fully seated in the fuse box.
- Verify the connection between the fuse tap's wire and the accessory's positive wire.
- Confirm the chosen fuse slot provides power when expected (e.g., ignition on).
- Original Circuit Not Working:
- Check the fuse in the lower slot of the fuse tap. If blown, replace it.
- Ensure the fuse tap is fully seated in the fuse box.
- Difficulty Inserting Fuses: The fuse slots are designed for a snug fit. Apply firm, even pressure. Do not force fuses, as this can damage the adapter or the fuse.
