Function:
Connects to the vehicle’s fuel pump circuit or ignition system (typically requires cutting one wire).
When triggered remotely (via SMS/app), it cuts off power to the fuel pump or ignition, stopping the engine.
Pros:
Simple installation (only 2 wires: power + fuel pump/ignition control).
Cost-effective for basic anti-theft applications.
Cons:
Limited to one control signal (either fuel or ignition, not both).
May not work on vehicles with advanced immobilizer systems.
Function:
Connects to both fuel pump and ignition circuits (2 control wires + 2 power wires).
Allows independent or simultaneous cutoff of fuel + ignition for enhanced security.
Pros:
More reliable for modern vehicles (bypasses some immobilizers).
Can completely disable the engine (fuel + spark).
Cons:
Requires professional installation (more wiring complexity).
