Perhaps it'll be clearer once I get it unpacked

Sorry for the confusion. That's partly because I wrote it up some time after installing it. The lead supplied with the camera has a USB connector on one end and a plug to go into the cigarette lighter at the other end. As Andycaca mentions, it has some 5V stepdown circuitry in it. It's therefore not possible to just hardwire it as I mentioned previously. That is where the cigarette lighter adaptor comes in (which I linked to in a previous post), and avoids having to muck around gutting the supplied cable.

The full wiring would be Camera - USB/cigarette lighter lead - cigarette lighter adaptor - piggy back fuse holder. It may not be a very elegant solution, but at least it's guaranteed to work, and only requires you connecting the red wire to the piggy back fuse holder and the black wire to a suitable earth.
