There might be a few things people *incorrectly* refer to as a kill switch:
* Inertia Switch (Fuel Pump Inertia Switch): This is a safety device that cuts power to the fuel pump in a collision. It's designed for safety, not as a convenient shut-off. It's usually located under the hood, often near the battery. Resetting it involves pressing a button. This is *not* intended as an on/off switch for normal operation.
* Aftermarket Add-ons: Someone might have added a hidden switch to cut power to the ignition system or fuel pump. Its location would entirely depend on where the installer placed it. You'd have to check wiring diagrams and possibly look for unusually placed switches or relays.
If you're looking for a way to remotely disable your vehicle for security purposes, you should consider a professionally installed immobilizer or alarm system, rather than trying to find or add a makeshift "kill switch." Improperly installed kill switches can be dangerous and create significant electrical issues.
