Where is the fuel kill switch for a 1994 Chrysler New Yorker?

There's no fuel kill switch as standard equipment on a 1994 Chrysler New Yorker. These types of switches are usually aftermarket additions for security purposes. If you think there *is* one, it's likely been installed by a previous owner and its location would be completely dependent on where they chose to put it. You'd have to look in various locations under the dash, in the engine compartment (though less likely for security reasons), or even in the trunk.
