Got mine today too! Guess the missed delivery notification I got was for something else.
I did mention that I need step by step instructions on how to set it up though, right? :p
Sorry, this weekend has been hectic and I've just got my first chance to sit down.
This explanation doesn't really need pics but I can post some if anyone is unsure.
Start with the power side. Most low voltage pumps will have a power supply that has a socket while the plug will be in a powe cable connected to the pump. If this is the case, plug the pump into the location maked power OUT.
I'm going to assume people are using the ebay plugs I linked to (though any plug will be fundamentally the same, though you may need to solder connections). Get a length of 2 core cable (an old power supply would be ideal, or if you have none lying round the house, jaycar sell some for about $1/m or less). Put a plug on each end of the cable. The cable colours will vary depending what you use but the important thing here is to make sure you connect + to + and - to -. Plug one end into the power supply and the other end into the socket marked power IN.
With the float switches, there are 2 the same and 1 that is different. The first 2 are the primary and secondary, the 3rd is the reservoir switch. If you don;t need longer cables on the float switches, simply attach a plug to the 2 wires, + and - don't matter here. Plug each switch into the correct socket. If you do need to extend the cables (which will be most people), simply get some 2 core wire (I'm using the stuff from Jaycar I mentioned above) and solder the wires together. Make sure you use some heat shrink on each connection and I'd recommend using a long length of heat shrink to cover the whole cable (or most of it) to make it a bit more water resistant (note this will not waterproof the connection and it will not be submersible, just splash resistant).
