My PC is down, otherwise I'd get a couple of pics for ya!
Basically, it's a push together joint that can be undone by pulling apart. You would just crimp the four wires into the connectors, and push them into the plastic holder. They are only about a quid, so not expensive, also you could do this at a later stage if you wanted, so don't panic. I should have myself back up and running over the weekend, so I'll get some pics up then.
