Changing Electric start to two kill buttons

[Woodsknight]

Topic says it all. How do I get rid of the bulky estart/headlight/turn signal unit switch and replace it with a kill button and an Estart button. I bought two Yamaha style kill switches. I wanna put a kill button on the left side and a kill button on the right side (this will be used for the Estart button). I understand that I will lose the high/low switch for the headlight. I dont care about that.
Hope someone can shed some light. Thanks
