Worked excellent. I have a Fusebox with a cover, so getting a Add-a-Fuse into it is a no go. This simply slips over one of the fuse terminals. I trimmed the top of the spade and soldered a wire to it (didn't use the terminals), and applied Gardner Bender LTB-400 4-Ounce Black Liquid Electrical Tape for insulation. Worked great.
