I took the horn off so there is no more horn haha. My new controls have headlight, blinkers, horn and pass. The horn and pass are not being used so I was hoping that one of those could be used as my ignition button. As of right now I have some big bulky button from O'reilly as my ignition and I figured that if I have 2 push style buttons not in use I could use one for that. It seems like it should work?
