Re: Add-A-Circuit for automotive fuse boxes
With the add-a-fuse (BTW, that price is waaayyy to high), you must ensure a really good ground as you are running only a hot wire. If you are going to run anything larger than 10 amps, I personally 1) ensure local ground 2) run a black ground wire back close to the fuse box. But then again, I'm a wire soldering maniac and love the smell of burning wire coating in the morning.
