Building a racing mower for fun we got a brand new Honda gxv530 for free but with none of the wiring harnesses and susch we have it all ready to go just need to rig a kill switch. I'm sure it has a stop engine diode where is it and how do i use it? We have the engine starting with a push button we hooked to the solenoid and it works fine but we have to disconnect the spark plugs to kill it I have a flip switch ready to wire but where do I wire it?
