Accele Electronics - Mini ATM Pigtail Fuse 15 AMP/12 pack
If you need to tap off of your car's fuse panel, this thing is indispensable. It absolutely fits right, it doesn't slip out or short out, and it does no damage whatsoever to the fuse panel. Remember to check with a voltmeter or test lamp before you insert it, and put your wire on the hot side not the fused side.
