I guess it unscrews - make sure you thread the wire through the sleeve before soldering (it's an easy mistake to make) L

My point was (from experience) make sure you don't have to unsolder it again cos you forgot to thread the sleeve...

The tip is hot/positive, solder to the center.
The sleeve, big part should be ground/negative, usually the big tab to solder to. It should be visible that it is in metal contact with the sleeve. Good luck.
