This 3.3 foot 12V add-a-circuit fuse tap adapter, compatible with car cigarette lighter circuits, is designed for safely adding extra electrical devices to a vehicles fuse box without modifying the original wiring system, ideal for car owners, DIY enthusiasts, and auto electricians who want to install accessories like dash cams, phone chargers, LED lights, or tire pressure monitors. The adapter is fully compatible with most 12V vehicle fuse boxes and cigarette lighter power circuits, matching standard blade fuse sizes to ensure a stable power supply while protecting both the original vehicle circuit and the newly added device from overcurrent damage.
Crafted with durable PVC insulation and high-conductivity copper wiring, the adapter can withstand the vibration and temperature fluctuations typical of vehicle engine bays and interiors, preventing short circuits or wire aging caused by wear and tear. The 3.3 foot wire length offers flexible routing, allowing you to place your accessory in a convenient position without being restricted by the fuse box location. The built-in fuse holder adds an extra layer of safety, and the plug-and-play design eliminates the need for complicated wiring work.
Simple Usage Guide- Locate the Fuse Box: Find your vehicles fuse box (usually under the dashboard or in the engine bay) and identify a spare fuse slot or a slot powering a non-essential component like the cigarette lighter.
- Install the Fuse Tap: Insert your vehicles original fuse into the top slot of the adapter, then insert a new fuse (matching the amperage of your accessory) into the bottom slot. Plug the adapter into the chosen fuse slot.
- Connect the Accessory: Route the adapters wire to your new device, then connect the positive and negative wires correctly (match the red wire to positive and black wire to negative or a ground point on the vehicle).
- Test the Device: Turn on the vehicles ignition and check if your accessory works properly. Ensure there are no signs of overheating or short circuits.
