Help Ignition wire help

[Keifer]

Hey All, thank you for the support for my last question. I have another probably simple question to ask. I changed out my ignition wires with a new set, the set came with 5 wires. I put the 4 into the four spark plugs and the last one is a shorter wire with a large 1 inch radius. I'm not sure what to do with it or where it goes. Any suggestions?
