How to Install a Hidden Kill Switch in your Car or Truck (Cheap Anti Theft System)

How to Install a Hidden Kill Switch in your Car or Truck (Cheap Anti Theft System)


Hey guys! ChrisFix here, and today I’m
going to show how to install a hidden kill switch in your car or your truck. And the whole point of this kill switch is to
prevent somebody from stealing your car. Even if they have your keys, if the kill switch
is activated, they won’t be able to start the car. They can try to hotwire the car, they can try
to jumpstart your car, push start it. This kill switch is going to prevent the car
from starting no matter what. The only way to steal your car is going to
be to tow it! And the best part is this is an inexpensive
thing to install. It’s going to cost less than $10, and it’s
going to take less than an hour. It’s super simple, it works on most vehicles. Even if you already have an alarm system,
this can work along with it. And it’s unfortunate that I even have to
make this video. I live in a pretty nice development. It’s pretty quiet here, everybody’s pretty
friendly. But recently, we’ve been having a lot of
break-ins. People are getting into cars broken into,
they’re getting stuff stolen out of them, There’s a few cars that have been stolen
from neighborhoods nearby. My buddy saved up for a long time to get
one of his favorite cars, a Honda S2000 in pristine condition, only to have it stolen and parted out a few
days later. Not only was he heartbroken about his car
getting stolen, but that feeling of helplessness and getting
taken advantage of by a criminal was horrible! Think of this relay as an on/off switch. When you put your key in the ignition and
turn it to the RUN position to start your car, the computer is telling the fuel pump relay
to turn on, and that is supplying power to the fuel
pump. Alright, so with our switch in, that works absolutely perfect. That’s so good. Now we can go and install this back in the
car. And back in the car, we need to run some
wire. We’re using 16-gauge wire. And we need to run it from right about here all the way under the dash to our fuel pump
relay. So I’m going to put the wire on the shifter
since that’s about where it’s going to end up. And it also makes it easier for us to run it
all the way to the relay. So make sure you have enough wire, then
we can cut it. And since we need 2 wires, use the wire
you just cut to measure the second wire. And we can cut it to the same length. Now let’s strip the ends of the wires. Add heat shrink to both wires. Then add the female spade connector and
crimp it. Then do the same for the other wire as
well. Finally, move the heat shrink over the entire
connector and use a heat gun to shrink the heat
shrink. Perfect, and I always like to run wires in a
wire loom to protect it from chafing. So just press the wires into the loom, and
work it all the way to the end of the loom. Good, now we can run our wires. Let’s snake this back behind the center
console area so it’s hidden and out of the way. Then we can connect our switch to each of
the connectors. Don’t worry, the order you connect these in
is not important. Just make sure the connection is good and
tight. And I’m going to add some electrical tape
to each connector to make sure it’s extra secure, and it’s shielded so it doesn’t
ground out by mistake. OK, so slide the loom all the way up to the
back of the switch so the wires are protected. Good. And finally, we can snap our center console
back into place and get the shift knob on. And let’s try out this switch… Beautiful! That is such a perfect spot for a kill switch! OK, now let’s finish running our wire to the
relay so we can try this out. Now when you’re running your cable down
here, you want to be very careful. You don’t want to get in the way of the
clutch, the brake, or the accelerator pedal. So you want to make sure this is up and
out of the way. So let’s get it up and over that metal brace, then up and over the steering column, and finally, tuck it behind the fuse box back
by the relay. And now with the wiring harness up and
out of the way, so it won’t get in the way of anything like
the pedals, we can connect our kill switch to the wires
that go to the relay. So here we’re going to use crimp butt
connectors. And when using these, you want to make
sure the copper goes all the way in. You don’t want any copper exposed like
that. If the copper sticks out into the clear area,
cut it and make sure the copper goes all the way in, just like that. Then we can crimp that side of the
connector. And finally, give it a good tug. Make sure this crimp is tight and the wire
won’t come out. And that’s in there good. Now let’s crimp the other side, and it’s the same process. Push the wire all the way in, then crimp it, and finally, we can heat shrink both sides
with the heat gun. So with that side done, now let’s go do the
other side. We’re going to follow the same exact
process, get that crimp connector in there, make sure there’s no copper showing, crimp down on it nice and tight, and then double-check to make sure it’s in
there good, and that is not budging. Now we can do the same thing to the wire
back here. And you can see right away the copper end
is WAY too long, so let’s trim it. Then add the butt connector. Perfect, crimp the connector nice and tight. Then do the pull test, and that’s not going
anywhere! So let’s heat shrink it for a waterproof seal, and the last thing I want to do is wrap the
harness in electrical tape to make it neat. Finally, we can push the connector into the
relay, and make sure you hear a click. Like that. Also, don’t forget to reconnect the negative
cable of the battery so we can test out our kill switch. Alright, with that battery connected, I didn’t
install the center console because if there’s any issues, it makes it easier, we just have
to pull this out to make sure we can fix whatever the issue
is. I don’t plan on there being any issues, but
it’s a good practice when you’re working on cars, don’t put everything back together
until you test it out. And that’s what we’re about to do right
now. Moment of truth, we’re in neutral. I think the switch is deactivated, so it
should be ready to start up. [Engine starts] Alright, it starts right up. Foot off the clutch, and we’re good to go. Now I’m going to shut the car. I’m going to flip our kill switch. And I’m going to start her back up. [Engine cranks] Woo, baby! Now that is what I’m talking about, and a criminal is going to be like, “What
the heck?!” “Why won’t it start?” [Engine cranks] Pumpin’ the gas, nothing. Flip that kill switch. [Engine starts] Starts right up! Oh man, that is exciting! So let’s finish this install up by adding our
last center console piece. And there’s a screw in here I’m going to
tighten down to hold the console in. Perfect, with the center console in, our kill
switch is in. Going to activate that so nobody can go
and start my car. We are done installing the kill switch, and
there is one more thing to do. And that is to install a home security
system to protect my tools, to protect my car, basically everything in
my garage. And it’s actually pretty cool how I got this
security system. I posted on my Instagram asking you guys
what do you do for security systems in your car to prevent your car from getting
stolen because of all these break-ins. And SimpliSafe actually commented on my
post and they sent me out this entire home security system, so thank you SimpliSafe
for supporting this video and sending me out an entire security system. So now let’s get this installed real quick. And the goal obviously is to protect the
garage and the new vehicle that I’m going to be putting in the garage, also the
vehicles outside. And this is very easy to set up. If you can put a kill switch in your car, you
can easily add another effective and reliable layer of security. Especially with these motion sensors and
this glass break sensor. And the feature that I’ve been wanting real
bad is a security camera. and then I have a security system ready to
go. And the reason why besides people
breaking in recently, The reason why I did this… …was because I ended up buying my
dream car! This mid-engine beast with AWD is
something I’ve wanted since I was a little kid, and I had to protect it. And I will unveil my dream car in my next
video, so stay tuned for that. If the video was helpful, remember to give

If any thief just understand the trick he doesn't actually have to find the switch indeed, I think that having the cutting point in the built in harness to close to the Rast connector they could just short that bridge

    Got to mention that all the wiring for this switch better be robust and won't come loose over time. Because the engine could turn off while driving in traffic since, in this kill method, the switch controls the relay which powers the fuel pump.

    Most people are very bad at making good wiring connections especially in moving vehicles were it requires extra precautions. Its understandable because most people don't work with this stuff and don't understand the smallest things like crimping on the right spot with the right force and matching wire gauge to the connector size. Otherwise, a good bump on the freeway will mean their engine shuts off while doing a freeway corner at 75+ mph. I"d like to also mention to make sure to use a quality switch. The little springs and joints in the switch can break down over time and over repeated uses causing the switch to have "play" in it. This again means the engine can turn off while driving. 🙁

    I might not recommend putting the switch in the flex area of the gear shifter because a driver's hand could slip off the shift knob and hit the switch. Or a passenger might place a hand or object there (just for a moment) and inadvertently toggle the switch causing the engine to turn off while driving.

    I install one on 2004 Chevy express are ,I used 14 gauge wire for whatever reason when I switch it on the ON position as I’m driving I noticed that the switch gets very hot to point where the connectors kind of melt a bit.

    I did not tap into the relay for the Killswitch. I tapped into the fuse from the fuel pump maybe that’s the issue or I think the main issue is the switch. I noticed the switch you’re using it looks like a heavy duty switch I think I’ll start with replacing that first.

    10:25 Instead of using two male connectors on the switch side for a MM/FF connection, use MF/MF for easy bypass. Like that you can connect both ends of the fuel injector line back together with access only to the center console. Great guide!

    Put it right in the front…and use an electronic number lock instead of switch with 6 digit combination. Right down a wrong password on a sticky note near it (I bet it's unavoidablly tempting to try that password for any new person/theif) and make the lock go nuts (shoot missiles, destroy neighbors or whatever) if this wrong password is input even once.

    You could have done a male & female on the kill switch along with a male & female coming from relay wire incase you wanted to get rid of the kill switch temporarily. This way you can connect the relay switch wires to themselves and have a working fuel pump when kill switch is temporarily removed/disabled 🙂

    Nice fix Chris! One suggestion. I would rather interrupt the circuit between the start relay and the start motor. Reason being, less chance of killing your battery or burning up a start motor. Plus a no crank lets the thieves know this car wont be so easy to steal. Like you said, being creative in your switch placement is KEY!
