An automotive fuse tap is a device used to add additional electrical accessories or devices to a vehicle's existing electrical system. It allows for easy and safe connection to an existing fuse in the fuse box, without the need for cutting or splicing into the vehicle's wiring. A fuse tap consists of a fuse holder and a wire with a connector on one end. The fuse holder is designed to fit into the existing fuse slot in the fuse box, while the wire connector is plugged into the accessory or device that needs power. The fuse tap works by using the existing fuse as a power source for the additional accessory. When the accessory is turned on, the current flows through the fuse tap, bypassing the original fuse, and powers the accessory. If there is a short circuit or overload, the original fuse will blow, protecting the vehicle's electrical system. Fuse taps are available in different sizes to fit different types of fuses, and they can be used for various purposes, such as adding extra lighting, audio equipment, or other electrical accessories to a vehicle. They are relatively easy to install and can be a convenient and safe way to add additional electrical components to a vehicle.
