I have a set of cold cathodes and a 3 prong LED rocker switch that I currently have hooked together.
You can find the rocker switch here: http://www.frozencpu.com/products/1911/ele-77/Red_LED_Rocker_Switch.html?tl=g44c153s315#blank
However, I can't figure out how to get the LED on the switch to light up when the cathodes are on.
I think the extra prong is the ground, but I still don't know how to set it up properly.

Can anyone explain in detail how to do so?
