Fuel pump cutoff switch

Has anyone installed one of these?

I am considering installing on of these somewhere hidden.
For those of you that don't know what i am talking about, this is a switch that goes in the power supply of the fuel pump. You would then place the switch in a hard to spot location that is still easy to access every time you get out of the vehicle. So, if someone goes to steal your FJ, they only get about 20 seconds away before the FJ no longer has gas going to it.

I mainly need to know what is the cable i need to tap into.
There are tons of people that have done this to other vehicles. I read this one guy had multiple switches that had to be in a certain order(up, up, down, up...), had to be pulling the highbeam switch and have the door open in order to start, if any of these were wrong it would blow a fuse and not be allowed to start. I don't want to go that crazy.

Just to install a simple on/off switch in-line with the fuel pump power, then mount it in some strange, hidden, yet easily accessible to me spot. I have already been thinking of spots to mount it.
p.s. im very sneaky.

Hm, i had another idea. Is there a way to install a cutoff switch to the starter??? Not in line from the battery to the starter(which is the large wire) but a wire similar in size to the fuel cut off.
That way they can't drive it any where, i.e. not even out of my driveway.

You should be able to break the low amp circuit to the starter solenoid.
