Has anyone made, or heard of, a device that plugs into the diagnostics port which disables the vehicle? You might use this when you park at the airport, or other semi-secure location. When you want to drive again, you simple unplug the device. Sure, a thief could pull the device out, also, but how many felons would be looking down at the OBD II as they were attempting to steal your ride?

 

All of them. Where do you think the wires live for hot wiring?

A disable switch could be installed.

 

Thanks. I'll go back into my cave and live my happy, but sheltered, existence.

 

I've thought about a kill switch rigged up to just the starter, but haven't got around to that project yet!
