how to replace sparkplug cap?

[Nevada Sixx]

hi, i got my new ignition parts in today, but my coil didnt come with the sparkplug cap,, just a wire coming out of it...
Are there any tricks or places where i could go wrong in trying to add a plug cap? Anyone got any experiance with this and have a tale to tell?

thanks.

All you have to do is buy a replacement cap and screw it into the wire. As soon as the cap doesn't tighten anymore then it is tightened good.
