Fuse taps can be used to help you quickly and easily integrate the ANY Hardwire Kit into your vehicle's electrical system,specifically the fuse box.
The fuse taps work by adding a new circuit to your existing fuse box. This is done by "piggy-backing" into an existing fuse slot. You simply remove the fuse from the slot you want to use, and put that fuse into the empty slot on the fuse tap. Then insert the fuse tap into the now-empty slot. 
The existing circuit integrity is not affected and retains its original fuse and functionality
 
These dont come with a fuse.
