Installing two kill switches in series

[Timmeh]

After purchasing a daily I am looking to track my car.
I am wanting to install two switches. One on a custom panel I am building for the tombstone and one through the rear garnish.

My idea is that in the event of a crash, the car usually would stall, in the event that it doesn't/ the impact creates a fire hazard, I want to be able to isolate the electrical supply and kill the motor. The idea for two is simple that if I am unconscious, the engine can be isolate from outside cockpit.

My understanding is that even with the battery isolated the engine will still run from the alternator so this would have to be isolated as well.

Has anyone got a schematic/diagram of installing a master kill switch that stops the engine and isolates the battery for and NA mx5.




thanks

Kill the power to the ecu/put in line with the switch on the barrel.
Look up CAMS manuals for a good idea of where to put the switch and how it should b secured.

I used the Cartek Battery Isolator, it is electronic (push a button) as opposed to manual (pull). The benefit is that I have a button in the cabin (within easy reach) and one as is required on the A pillar. It is also possible to add additional kill buttons as required.

As I understand it you need to be a little careful with how you kill the power on modern cars as the alternator or ecu can be damaged if the power is cut with engine running.
