I am getting ready to purchase a wire kit. The three places I am looking at are Rebel wire, they have a rear trunk kit that looks good, Painless wiring and EZ wire. I am looking at the 21 circuit. My question is I won't use all the circuits, what do I do with the extra wire? Cut the wire and don't install fuse ???? I am wiring a 55 ford F-100 Panel with a few modern additions is why I need the extra circuits, and is a litttle more involved than my past projects.
