For it to work at least on the LE's you need to put an LED bulb in.
Green goes to center of switch. Diode wiring is in the instructions. The wire with the black shrink wrap will need to be soldered to the other side of the switch.
You should then be left with 2 wires. I do not think it matters how they are hooked to the light socket. Though you can test it. I have found the new buttons do not work on LEs without the LED bulb.
