So from reading the link.

I could use a servo to operate the choke instead of a using remote operated kill switch. But in either case a remote controlled shut off is advisable. Whether it is a slide switch controlled by a servo, choke controlled by a servo or a new special opto isolated ignition kill switch. The opto controlled switch having the advantage of less possible ignition interference because it is easier to maintain a 12" separation from the receiver.

Next, use a heavy duty switch harness so I can manually turn off the power to the ignition and have a port to charge the ignition battery.

Then try to keep everything electronic 12 inches away from the ignition and use no metal to metal linkages.

Got it.
Thanks,
John
