On the back of the switch, you'll see 3 terminals on most of them, four on the older ones. One is 12V pos, the other is accessory and the third is the power supply that gets activated with the switch when you have it unlocked with the key. If you jump the +12 and the ignition leads it should start when you press the start button. If you choose the accessory leads, it will not start but you should get some tail lights lighting.
Sorry but I don't have a wiring diag for your bike to tell you which colors they are. Look for markings on the terminals themselves, some are marked.
You'll know when you bridged the right terminals by hitting the starter button, it should crank and start.
