I bought the Painless 7 circuit Isolator & have 1 question for now. It says to find a switched fuse & use their tap to hook onto the hot side of it. It is dark outside right now so I can't check, but it looks like the kit has a tap that fits the larger style of fuses & not the itty bitty ones that are in mine. Is there a way to make it work?

Also, is there a way to make a blank slot (no power @ all) into the current fuse panel?
