wiring for both button and ign switch for kill

[bocakart]

Im working on a honda clone..(not Predator) Ive wired the ignition switch to act as the engine kill and to power electric start button. How would I wire a "push button" kill switch into the circuit to give me the option of using the key or the button to kill engine. Right now if the key is in the "off" position...the coil is grounded (wont start) once the key is turned to on....it opens the circuit and it will start. If I put the button anywhere in that circuit it will always be open(until its pushed to kill) meaning the engine will be able to start without the key being turned...

thanks...kart is an older Hammerhead 80t 196cc 6.5 hp

If it has a low oil relay intact still, unplug that from the lead going to the block... Wire inline to ground a momentary on pushbutton switch, from the little gold box relay. Mount the switch anywhere you want...
Kills instantly no studdering... Main switch is unaffected...
