1. Ignition Wire Kill Switch

An in-line ignition cut-off switch can be a genuinely efficient option for protecting an automobile. You should find spaces around the car seat or in the area under the dashboard. These places are efficient in incorporating a hidden toggle button or physical switch.

This allows for quick and easy access when exiting or entering the vehicle. For this method to work, the cable is a switch. This is precisely where the key turns. The most important wire is the wire coming out of the automobile’s ignition switch. People often use a wiring diagram of the car.

It would be best if you got the wire from the ignition wire. You also need to choose the best wire to be able to cut and incorporate the components. The user cuts the ignition wire and includes the switch in the middle to toggle on and off the current essentially killing the current. 

Soldering is not the only option that is available to complete this procedure. Additional connectors can also be in use to crimp each of these parts. Once the user incorporates everything necessary, the kill switch will have physical functionality. 

2. Fuse Box Kill Switch

People have also used the fuse bypass switch. This is a very efficient method to prevent car theft, and it is simply a fuse. The vehicle owner must remove the indicated fuse to prevent the car from being able to start. It is necessary to remove the fuel pump fuse or the ignition fuse.

Some vehicles have a fuse box that is hidden or difficult to access. Users do not want to access the fuse box every time they want to protect the vehicle. The user can place a fuse bypass switch in an easily accessible area.

This switch can turn a specific fuse on and off to protect the vehicle efficiently. There is a disadvantage to this particular configuration. The result may have a fuse box and a wire that sticks out a bit. The result could be somewhat apparent to those who wish to steel the vehicle.

The protruding cable can also be an obstacle to install the fuse box cover fully. The user connects two female spade quick-release clamps. The person also connects one of them to another similar unit via a cable.

The connection of the other is to an in-line fuse cable to reconnect it to a similar unit. The person incorporates the 12 V toggle switch.

3. Remote Controlled Car Battery Switch

This technique makes it possible to disconnect a vehicle regularly and conveniently in just a few seconds. People do not need to go under the hood to be able to deactivate the battery. Users avoid this because they think they have to remove the battery cables or turn a specific knob under the hood.

Complete parts kits are available to incorporate a remote car battery switch. For this task, the user has a latching relay along with other valuable parts. This method only requires power at the time of turning off or on. 

The vehicle battery is not exposed to constant discharge. The parts kit is installed on the battery. Different instructions often vary, and this depends on the exact model of each parts kit. It is a series of simple steps together with the operation of the remote control. In a nutshell, you use the remote control to disable a vehicle. 

4. Fuel Line Shut-Off Valves

This method requires a fuel cutoff switch. The driver prevents the vehicle from having the fuel supply start. Most of the time, thieves think that the car has engine problems. A car that does not have fuel cannot start.

The owner of the vehicle goes under the car to find the fuel line. The same person must cut the fuel line in half to install the device. Doing the job quickly avoids a large gas leak. Small hose clamps are necessary to complete this procedure.

This is not the best option available today. It is especially not a suitable option for those vehicles in daily use. It is still an efficient option for cars that go into storage for some time. This is because it is necessary to get under the vehicle every time it is not in use.
