How To Install a Kill Switch In Your Car!

[@chrisgraham2904]

I would NEVER recommend wiring a kill switch to the fuel pump. Failure of the switch, any wired connection or accidentally bumping the switch while driving will shut down the engine and cause power steering and power braking systems to fail. The result could be catastrophic at highway speeds. Wiring the kill switch to the ignition system to prevent "start up" is a far better and safer option that will perform just as well, or better. Wiring a kill switch is a relatively cheap security measure anyways, so I highly recommend to use only a quality 'military grade', or 'aircraft grade' switch by a reputable manufacturer, such as Honeywell and others. A $20 to $40 dollar quality switch is cheap insurance against a $3 dollar cheap, Chinese switch which is intended for minor, non-critical lighting applications. Insure that every connection in the circuit is soldered and sealed to be bullet proof and protect all wiring with quality wire loom. Don't sacrifice safety for security.

[@sandyhill8935]

I agree! This would be a safety recall if any Car manufacturers ECM did this by mistake, so don't do this it's dangerous.

[@ec53001]

I would not recommend using the roof light for the kill switch. If someone is unaware and uses that light while on the interstate at a high speed, it could be very dangerous.

[@grandiewandie]

@D Mwhile that is what Interstate means, its generally just used as slang for any high speed freeway.

Hello 2020 viewers. Remember to always disconnect the battery when doing electrical work on your car. Necessary to test which wire for this method but disconnect after you know which wire is correct.

[@villigance264]

@Langston Kyle any luck?

[@inductor1.77]

You added a long run of much smaller wire gauge to the circuit. Aside from it possibly not being able to handle the current and heating up/melting it would also lower the voltage the pump recieves. If you do this, you should use a thicker gauge run wire than the one you cut into.

[@ohyea2723]

It’s definitely a great video all other videos have the kill switch going to the fuse box which is a waste. Question What gage wire would you recommend what gauge switch and what gauge connectors. Thanks

[@inductor1.77]

@@ohyea2723 I would check the gauge on the wire you're splicing into, it should be written in small letters on the insulation and use one size larger (a larger wire size will be a lower number). Once you know the gauge of the wire youre splicing into just google a chart for amperage that the wire is rated for. Find a switch with the same amp rating or higher. But youd probly be fine to use 16 awg stranded and a DC switch of 10A.

[@ohyea2723]

[@saomychau7010]

Yes, I also noticed that he used some small wires for extension of the connection, especially for a power fuel pump circuit and it could heat up later on (say, after 10 minutes?) In my case I approached the fuel injector fuse and make the tap for a 'wire tension', rated 20A fuse in the engine compartment, and under the hood, so I must use a 12 AWG wire pair and an inline fuse-holder with a 20A fuse, as things are heated up to some temperatures under the hood and the fuse could be burned out easily if not of the same rating.

[@saomychau7010]

I had watched several KZbin shows on how to install a kill switch to cut off fuel to the car, and one way is to approach the fuel relay under the dash and insert the wire extension to the power input into the fuel relay. Your method is moving the wire extension as close to the fuel pump as possible and under the back seat. I think this is much easier access for you to do the installation. In any case, the installer/operator of the vehicle got to know where the "hidden Kill Switch" is located, and I think in your case it is among the hardest to find. I personally approached the 'harder way' by locating the fuel injector fuse in the fuse box in the engine compartment or under the hood, and this pose a challenge of passing the wiring through the firewall and that requiring an elaborate process of drilling a hole through the metal and also adding additional layer of insultation by electrical tape. Of course, I can hide all the wires and the switch very well, but its utility was hampered, because it is not so accessible from the driver seat. I am still thinking on finding a 'better' position to place the switch, and since each car is different if it is not the same brand or a similar model. Today, I also saw one person approach the kill switch installation 'solution' this way, but the fuse box is inside the car cabin of the old Honda sedan. Moreover, I had done this in an SUV for my wife and I have not told her of this, except to mention briefly that I would put a kill switch for her many months ago. Of course, in all cases different people were meticulous that they insert a line fuse holder and a fuse to protect the circuit if they had based on the line insertion at the fuse box, and including myself for doing this. One thing I am so concerned about the fuse rating in my case is it is rated 20A and that required the 12 gauge wire (12 AWG, American Wire Gauge) and that is a thicker wire. Initially, I tested this out by using only a 16 AWG wire and it seem to be no problem, but I thought they must have a need for higher current and so I replaced with 12 AWG wires, because there are six (6) cylinders and the injectors need a lot of current to spray fuel into a fine mist, as it is directed inside the port of each cylinder head for the compression cycle to take place before firing up the fuel vapor (trapped between the cylinder and the cylinder head.)

[@leecowell8165]

I thought of that. But on the Kia Soul that fuse panel is VERY to access. The bad guy could pull the cover and maybe have a spare fuse or even jumper lead to bypass it. However I'm thinking that's the route I'm gonna take because these perps are in a hurry. And even if they discover the issue WOULD they be smart enough to figure it out and especially if you GLUED the jumper into the fuse panel so that it could not be easily removed?

[@danielramsey1959]

One good place to install the kill switch is near the seat belt release in case of a carjacking.

[@tomatexelon]

There is good and bad ideas about this switch on the fuel pump, If the thief hotwires you vehicle or even if they have the keys! They WILL be able to drive for a short time ~15 seconds or so depending on vehicle and then the vehicle will be stalled in the middle of the road. This may cause a major road blockage without you even knowing. Maybe but the switch on the ignition start relay instead so that it wont even start. But, something is better then nothing!!!!

[@nikopriest3905]

Thats how i usually do it. Interrupt the starter relay so you dont even get to drive off. Plus i've heard so many stories of clients pressing the kill switch by accident and the car shutting off while driving (once hooked up to the fuel pump). So it's way better to interrupt the starter, its safer and more efficient.

[@bobbyatman273]

If you want your would be car thief to get stuck in the middle of the road around your corner - you install a fuel pump kill switch, you can install switch to the pump itself or at the relay or fuse under hood or fuse box, if you want your car to not start at all you install the kill switch to the starter, but if the car wont start the robber might just spend some time to remove things or just to vandalise it. Take your pick

[@joshspades9031]

Thanks I needed this; I was thinking of getting a multiple switch box (like 3 or 4) for several things. One of them being a license plate flipper so itd be cool to match the car at shows/meets for the occasion. One of them being a fuel switch (so it sounds like it's running out of gas when I don't want to drive someone far/a distance if I'm being a good samaritan giving a homeless person a ride [especially from their ill intent) I hate wires and electrical. So its great to read this and get a better understanding Thank you

The problem with that is that it will reset your radio and your car's adaptive learning every time you switch it off. It's better to wire the switch to the fuel pump.

you have to turn it off manually each time, its just like a light switch. if you leave it on then the car will start every time, if you turn it off the car will not start.

u coud use a small relay (with a switch) as wel and wire it that it turns of when power gets cutted

[@DJdavefromlondon]

@@Danny-pp8xz I understand basic 5 pole relay, the kill switch is on the low amp side to trigger the relay switch. , the fuel pump is on the high amp side with gnition key, So if kill switch is off then relay switch is also off even if you have the ignition key and try to start the car. You could also wire the 5th relay pole to the horn so if ignition key is used but kill is off then the horn will sound until kill switch is on. ....... but I don't understand how a relay could solve the question asked ie when you leave the car and forget to switch kill off .

Can u do wireless kill switch

[@TheFittingBay]

Healthy Life not on the fuel line. Actually nothing wireless as a decent solution at all. Wired = better

[@mannys9130]

You could probably construct a wireless kill switch apparatus if you're a bit more advanced in electronics. You could sit down and look at your car's wiring diagrams on AllData and find a way to put something together to interrupt the fuel pump power using a relay controlled by a wireless actuator or maybe a wireless Arduino or Raspberry π receiver. It would be a good idea to also try to incorporate a self-latching relay design with a second relay powered by an ignition hot circuit so that once the car is started the fuel pump cannot be turned off by an accidentally bumped wireless remote or local RF interference. Once you turn off the key or push an enable button, the self latching system would get cut off and you could enable the kill switch again to interrupt the fuel pump power wire and kill the car. It would take some thinking, part sourcing, and a few hours assembling the device and installing it in the vehicle. Most people fall in a double bell curve though...the ones who want a kill switch do it cheap, quick, and simple like this. The ones who want wireless systems pay an installer for a Viper or other advanced security system. Not many people fall in the center of that wishing to build their own simple wireless kill switch.

[@iceegogaming8060]

Don’t probe wires moisture will get in the wire and cause to to corrode out

[@mannys9130]

Correct. If you must stab probe a wire, put a dab of liquid electrical tape or RTV silicone over the injury to seal it back up. It's best to back-probe a wire with a T pin or a sewing pin if you need to put a VOM on the wire. Sometimes it's just not possible to get to a connector though. I also don't recommend the T-Tap type connectors that just clip onto a wire and stab through the insulation to make a new connection because they can fail for the same reason (and it's a poor connection to begin with).
