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! So that is exactly why I'm going to be
showing all of you guys how to install a kill switch, so you don't have to feel that way. You don't have to lose your car. Also, a lot of people are stealing stuff from
garages (don't look at that garage, it's a mess), so I'm also going to be installing a
SimpliSafe security system. I've got a camera, I've got a bunch of
sensors, all that good stuff, so the garage is gonna be protected and the cars are
gonna be protected. And here's all the tools that you need, it's
super basic. We have a switch, we have crimp
connectors, we have 16-gauge wiring. You need a multimeter, crimpers, wire
strippers, heat gun, and, as always, when you're working on a
car, make sure you wear your safety glasses. So enough talking, let me go show you how
to install a kill switch. And to start, you're gonna want to know the
basics on how this is gonna work. So the kill switch that we're going to install
is gonna cut the power to the fuel pump relay. So this right here is the car battery. It supplies the 12V through the relay into
the fuel pump. So our fuel pump is pumping fuel into the
engine and the engine will run. 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. So what we're gonna do is we're gonna
splice in our kill switch right here. That way, when our kill switch is activated,
it cuts the circuit. The computer cannot send a signal to this
relay, and this relay will not send power to the fuel pump. Therefore, the car won't start. It's really simple. All you need to do is find the fuel pump
relay, and I'll show you how to do that right now. Now the fuel pump relay is located in
different spots for different vehicles. It'll be different in this Honda compared to
this truck, and so on and so forth. To find your fuel pump relay, just check
your owner's manual, check the service manual, do a quick online search, "1993
Honda Del Sol fuel pump relay location", or whatever your vehicle is. In this case, it is right under the dash, let
me show you right down here. You can see right here is our fuse box. A lot of the times, the relay's in the fuse
box. But in this case, Honda puts their relays
back here. Here are all the different relays. And this gray relay right here is the fuel
pump relay for this Honda. Now if you're not 100% sure if this is the
correct relay, one thing that you can do to test, is to put your fingers on it. And when we turn the key to the RUN
position, the relay should click on. [click] You'll hear the fuel pump run for a couple
seconds, and then it'll click off because the fuel
pump is primed. I can feel it, and I can hear it, so I know for
sure this is the correct relay. Now to disconnect the wiring harness, you
just press in this tab right here with your fingers, and wiggle this back and forth. Like that, and pull it out. Never pull from the wires, always pull from
the connector so we don't damage anything. And as you can tell, there's a ton of wires
here, so how do we know which one we need to tap into with our kill switch? Well, it's pretty easy to figure out. Let me go show you how to do that now. So grab a multimeter. I'm gonna set it down right here. And we'll start by connecting the black
probe to a ground. So we need to find a bare metal surface,
like this. And right here, you can see a nice bare
metal surface which is holding our hood release in. So grab your ground wire and connect it
right to that chassis ground. And now our multimeter is grounded. And now we're gonna grab our multimeter
and turn it on to DC volts. You want to set it to 20 DC volts because
12 volts is the highest we're gonna see. Now we're gonna take our red probe and
what we're gonna do is we need to find which of these wires is gonna be hot, is
gonna be on providing 12V when the car is in the RUN position only. So when we turn the key, we get 12V. That's the wire coming from the computer
going to this, triggering that relay. But before we turn the car to the RUN
position, we just wanna check real quick with the car off if any of these are 12V. If we find one that's 12 volts, we can ignore
that wire. That one is hot all the time. And that's what the relay's gonna connect
to, to power the fuel pump. So the top right corner is hot all the time,
12V all the time. We don't have to worry about that one. Now let's turn the car to the RUN position. So now with the key in the RUN position,
we're gonna probe each one of these and just see which one is gonna be our
trigger wire, our 12V. There we go, so we have 12V with this one
right here. I just wanna check the others just to
double-check and make sure. Good, no voltage, and obviously, this one
will be 12V, that's always hot. So this one right here, I'm gonna probe, I'm
gonna push this in. That one is 12V with the key on. If I shut the key, it goes down to 0 volts. When I turn the key on, it goes back up to 12 volts. So we wanna follow that probe into the
wire, the probe's at the top here. So it's this wire right here. You can see that's the correct wire. That is the wire that is coming from the
computer and then triggering our relay to turn it on to give power to the fuel pump. So we need to splice into this wire right
here. Now before we go cutting any wires any
time you work with the wiring harness, we wanna go under the hood and remove
the negative cable from the battery. This will just prevent anything from
shorting out or blowing any fuses. And it's what you wanna do any time you
work on an electrical system. Now splicing into the factory harness is
gonna be the part that most people are apprehensive about. They don't wanna do it because, well, what
happens if you do something wrong? But don't worry, this is really easy! Here's a few quick tips. First, you don't want to cut near the
connector. You also don't want to cut near the end
here, you want to cut in the middle so you have a lot of room on both sides to work
and splice in a new wire. So we're gonna cut right here. Good. So now grab your wire strippers. These are automatic wire strippers that
makes it nice and easy in these tight areas. You just clamp down, and it strips it right off. So that's one side done. Let me give you a closer look when we do
the other side. You just put the wire where you want it to
get stripped. And the automatic wire stripper does its
job. Beautiful! So now that both of our ends are stripped,
we can add our kill switch. But we're not gonna wanna add the kill
switch right here. We wanna hide our kill switch which is not
gonna be right next to this. So when hiding your kill switch, there's two
things you wanna think about. The first thing, you wanna put it in a place
that's easy to get to. Somewhere, you don't have to reach all the
way into the glove box every time and fiddle around. You're gonna be doing this every time you
go to start your car. So you wanna make it simple to get to. Now with it being simple to get to, you don't
wanna make it easy to find. So you don't wanna just put it under the
dash where the criminal's gonna look. That's like the first place when they can't go
to start the car, they're gonna feel for switches down here. So don't put it under the dash, you wanna
find someplace hidden, someplace where, you know, they're not likely to look. The radio's actually not a good idea,
because a lot of criminals when they can't steal your car, they're gonna try to steal
your radio. But a lot of people like to put it underneath
the seat, you have to reach somewhere. It's harder to find. It's easy to get to. Another place is the glove box. Again, if you have stuff in here, it's harder to
find, but it's easy to get to. Get creative, this is the part where you can
have some fun! So I'm gonna share with you my spot. I'm gonna end up having to change it
because millions of you are gonna see this. But my spot, which I think is a really cool
creative idea is in the shifter boot. So underneath the shifter boot, we're
gonna find a spot. You can't see the switch, but you can easily
feel it and turn it on and off. So that's where we're gonna place our kill
switch. But again, be creative! Have fun with this. Place it somewhere unique. So since I told you we're gonna put it right
here, this is where we're gonna go and run our wires from. So let's take the center console apart. Since the previous owner never put the
screws back into the console, it lifts right out. Same with the front part of the console. Oh, we gotta unscrew the shift knob first. Good. Now the console will come out the rest of
the way. And check this out! We have a flat surface down here, and a flat surface up here to mount the
switch into. Now we wanna unscrew the two screws
holding in the shifter boot. That's one. And let's get the other. Good. And now the shifter boot comes right out
just like that. Next, let's grab the switch and match it up
to see if it'll fit. And that's looking pretty good right there. So let's make a mark in the middle here. Then grab a centerpunch and we want to
indent the spot we just marked. And what this does is it puts a little
indentation. That way, when we get our drill bit, the drill
bit won't skip around, it falls right into that indentation, and it won't move at all so it
makes it a lot easier to drill. So we're gonna start with this small drill bit, and then we're gonna work our way up to
this bigger one. So on a slow speed and with some decent
pressure, let's get the first hole drilled out. Now with the bigger drill bit, let's drill the
hole out to fit the switch. Good. Now we can test fit our switch. Beautiful, now we can add our On/Off
plate. This is gonna act more like a washer since
we're not actually gonna be able to see this. Then I'm gonna add a little bit of thread
locker on here just so our switch doesn't come loose. And then we have our locking nut which
goes right on the end and we can tighten this down. And our switch works great, that's perfect! The only thing that I'm concerned about is, these wires right here against this metal
surface. Over time, they could chafe, and that can
short out, we could break a wire, and then we wouldn't be able to start our car. So what I'm gonna do is I'm gonna get a
little rubber wire protector, and I'm gonna just slide this over the wires. I'll slide that down, And you can see, now it's protected so our
wires won't chafe. We'll add a little bit of black tape to hold
that in place, and that is good to go. Now the last thing we need to do is we
need to make a quick disconnect. That way, if we ever need to remove this
interior piece, we can easily just disconnect this. And to do that, we're gonna use these
crimp-on spade connectors. All they do is they slide right in, and there's
a good connection there. And then when you wanna separate it... They come right apart. So we're gonna put two of the male spade
connectors on the end here. But first, let's add some heat shrinking on
each wire. Then we can push on our spade connector. Crimp it so there's a good connection, and
so this doesn't come loose. Move the heat shrink up over the
connector. Finally, use a heat gun to shrink the heat
shrink. And do the same exact thing to the other
spade connector. Push it on, crimp it, move the heat shrink up, and use a heat gun to shrink the heat
shrink. And there we go, now we have two quick
disconnects, spade connectors that are properly crimped and heat shrinked on
there. 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 I have it pointed to the most important
part, my driveway, so I can keep an eye on all my vehicles. And I think you guys get the idea. Now I'm going to install the rest of this off-
camera so you don't have to watch me. I did check online because this was sent to
me. I wanted to see how the pricing was and it
was pretty fair, they also have no contracts, and finally, I do have mine
monitored by professionals. So if somebody breaks in, they will call the
cops and the cops will come, which is good. So all my cars, my tools, all that stuff is
protected. Now we have all the cars, I need to put kill
switches in the rest of them, but all of the cars have kill switches in them 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. [Series of engine revs] And I will unveil my dream car in my next
video, so stay tuned for that. I think you guys are finally understanding
why I've been getting so crazy with the security stuff, with a home security
system, installing kill switches in your vehicle. I hope this video helpful, I hope you learned
how to install a simple kill switch. Very cheap, very effective. If the video was helpful, remember to give

Hey GUYYYSS Chrisfix here
anyone got any idea on an effective anti-theft device for my 84 chevy k10? other than it looking like a beater right now
Huh. Here I thought one of the more clever ways to kill switch your car was to identify and pull the fuel pump fuse. A would-be thief is unlikely to try to diagnose and fix an issue like that.
Chris bought a Previa?
New dream car is a Hummer H1. Specifically with a civilian conversion
On a classic run an msd system. Run your ignition wire to the box for accessory. Won’t be hot under crank. Hook up a second power source that you control to provide 12v under cranking. All looks like it’s hooked up to the normal eye but won’t start. But your also talking to a guy that has chained his steering wheel to his brake pedal and also bought his msd box in with him in certain areas.
as a guy with a car wit an electronic throttle body, ecu reset fucks up my throttle response for next 15 minutes.
This looks like a great way to get your dashboard to light up with all it’s fun lights.
