The yellow, green, red, lines go to the tac switch replacing the slider "medium press". The purple and blue dots go to the "full press" spots, you'll need a separate tac switch for them. Then its just a matter of trickery and witchcraft to get them to work buy stacking the "medium press" and "full press" tac switchs so a light press only push the "medium press" and a hard press will push both.
