Each set come in two pieces about 2 feet long. Most mistakes are trying to use one piece. When connecting two wires as a splice make sure they dont touch ends keep a few inches apart. Braid or wrap one half of the wire splice around both ends of the mainline, the last wrap will be hard and it will “set” onto the wire. For the second half, you MUST start in the middle where the little paint marks are. Line up the paint marks and simply braid the splice outward to the ends until they set as well. Each half will braid in a separate direction. Once attached they will never come apart.
Hopefully that makes sense? If not maybe OneLegJohn can video it.
