wiring casa ignition switch problem

Hi i am having trouble wiring a ignition switch . I am trying to wire to a li type switch (with side lights on the switch) i am taking it that purple is the feed for yellow and black (side and back light) on position 2 and brown is a feed for orange (main lights) on position 3.
What i would like to do if possible is to still use the original switch as well as the key positions on the lock
I know the switch is designed to work through the sx type switch with no side light switch on the handlebars
