What Are Fuse Taps Used For?
Model: (Various brands) Various
Video tutorial
Fuse taps are very useful accessories for adding electrical circuits to your car's fuse box easily and safely, without cutting or stripping original wires. They are used to draw 12V power from the fuse box to power new devices (dash cams, sensors, amplifiers, etc.) or to create a new parallel electrical circuit without compromising the original circuit. The tap fits into a slot in the fuse box in place of the original fuse and has two slots: one for the original circuit and one for the new added device. It has a 12V positive output cable to connect to the new device and often a ground cable to attach to the bodywork. Pay attention to the orientation, as the taps have a specific orientation: the common leg must be inserted into the slot that provides power; if inserted the wrong way, the circuit will not be protected! To find the correct orientation, you will need a multimeter to find the "+12V" side of the slot or try to test its operation.
