Low volt lights

Hi,

Just got 6 low volt lights for over the top of our robes, they came with 2 transformers which don't have connectors on :(

so they both have power and then 2 white wire out where the lights connect to.

Whats best way to wire them? they will be plugged in with an in line switch but I only want one wire going to the plug if that makes sense.

Also what connector blocks do I need to get for the lights to plug into as you can tell I have no ideas :)
