Sabvoton 72150 ignition/alarm wiring

First of all, I know probably the following question I have may have been answered before way back when....just a bit lazy to scroll and also tried the search but no avail. I have the 72150 controller. All I want to know is how to wire my ignition switch to it. I know there is that orange wire that hooks to the positive and you can hook up a basic on/off switch. I have a key ignition that has the red/black/green wires. Am I supposed to hook up the green to that orange wire instead of the orange wire going to the positive side of the controller and then hooking up the red and black to the positive and negative side of the controller? Also I am wanting to hook up the cheap alarm module that enables and disables the ignition like on an Onyx bike. How would I go about doing that if I am to do that in future. Right now I just want the key ignition. Thanks all for the help.
