Avoid Ciggie plugs if you can. They have a nasty habbit of losing contact when you least want them to. The spring in the fuse holder sometimes causes them to push out a little and then things start turning off when you dont want them to.
Make or buy a decent DC junction box with decent connectors. Something like one of these

You can then get some Anderson Power Pole Connectors.

You can buy these in AU and the connectors can also be found on ebay nice and cheap. Here they are at Jaycar
