Is there a fuel cut off inertia switch on the CL?

I want to wire in a hidden toggle switch.

I did this on my explorer & it works very well to disable all fuel so the car will not start in any state.

there isnt one that i know of like the units found on the fords.

wire a switch to the starter solenoid

i was also thinking about something along these lines. has anyone done this yet? or have any info/pics?

I'll have dig into my service manual this weekend & see where it could be added.
It was a whole10 min job on my explorer.

i was thinking of doing the same... better to be safe than sorry. plus it should be simple enough to do.
