roadster2 electrical light switch

[oldschool71]

I am rewiring my rupp roadster2 today was looking at the diagram for
the light switch. Not sure if i have it set up right. anyone have a easy diagram pic that shows the back of their switch. there are 5 wires and seem to be 2 empty holes. not sure if I have the configuration correct before i mount this
on the handle bars. the colors are yellow, black, blue, green and red.
What is the purpose of the button on the top.?? the side button is the kill switch.
thanks oldschool71
