These fuse taps (also known as ‘add-a-circuits’) will allow for non-invasive installation of a dash cam or almost any other electrical accessory into your vehicle. No cutting of wires or splicing is required, you simply crimp a fuse tap on the end of your accessory device's bare wire, then plug and play at the fuse box. Take the pain out of 'hard-wiring' with our simple fuse taps. Please select the correct fuse tap for your vehicle using the product's drop down box.
