anti-theft save your truck from getting stoen

[rigo_jones]

Theres been a lot of threads about good people getting their truck stolen. I've been there myself so many times that i decided to do this.

I'm sure some of you know this but some dont and I think this works better than a clubstick or a simple alarm. It will take you about 20-30mn depending on knowledge but is simple to do. I've had 2 hondas stolen and 1 that they tried to take but with this mod they couldn't.

First what a thief does(did to my cars) is see if it has alarm... obvious if it does he will go to the front of the car/truck, there he will look for the hood latch cable cut it, open your hood and disconnect/cut the battery cable. But wait, you have a hood trigger sensor. Well a good known thief will need less than 5 seconds to pop open the hood and quickly cut the battery wire. Now say they cut the wire and alarm will deactivate but some good alarms have a relay that activates if the alarms power was cut, and when activated so if they plug the battery back the truck will still not run because the alarm has the relay activated.

But of coarse any thief knows that so they look for the alarm and gut it before connecting the battery back. Now all they got to do is break the ignition switch some how and drive off. This happens in less than 3 minutes, less if theres more than one thief. with this mod the car/truck will not crank even if they cut the battery, change computer, gut the alarm or brake the ignition switch.


You will need a switch that is rated to equal or more of the amps of either the fuel pump or crank fuse. You see where I'm going with this?:naughty:

Find the fuse that disables the fuel pump or cranking. Our GMs only have a fuse labeled crank this should do it. For any manual transmission car/truck use fuel pump fuse.

You can find a fuse holder like this or just splice your harness. Make sure you keep a fuse in line with the switch in same size as oem.

The last step is to find a hiding spot for your switch. Make sure no one can see you activate it not even friends/thief:blah:. Usually is best somewhere where you can activate it with your foot.

Thats it!!!:cheers:

Keep in mind that if you have remote start, this will prevent your truck/car from starting if switch is activated. But you can always activate it in an unknown area to you.

btw I had 3 of these on each of my hondas deactivating the fuel pump, ecu, and distributor. But you only need 1.

hey rigo this is a good idea..where can i get that type of fuse holder with that pulg end?? radio shack,auto zone???

[rigo_jones]

aether but check autozone first.

[Narco]

pretty interesting

[Rivieraracing]

I have basically the same setup on one of my current rigs and have done it to 2 others in the past, works very well!!

You can use a 5 pin Bosche/Tyco relay to close the circuit when remote start cranking, and then use any low amp switch for the relay. You can then use a momentary pressure switch under the carpet.

Even better if you do ignition instead of crank, because then they can't valet the alarm, something far too easy to do otherwise.

At Music Systems, used to do an alarm controlled ignition interrupt.
Using an aux channel on the alarm, you would have to connect the ignition or the truck obviously wouldn't start. You couldn't go to valet mode, because ignition on is required for that. If the alarm was unplugged, there was no way to connect the missing ignition circuit. It cut the theft rate here from ~two h2/Eskys a week to nearly 0 a year.

yeah i was thinking of that relay so you can still have your remote start but too complicated to explain and build one since theres a lot of different alarms out there.

keep in mind that once a thief gets inside your truck/car the 1st thing hes going to do is look for the alarm and unplug or cut all the wires so there will be no more alarm.

*i did try the ignition fuse but it still turned on after removing the fuse. i tried the crank and it didnt start. remember not to tell anyone keep it to your self and wife or your girlfriend if you trust her enough. all it takes is one lil fight to get payback. lol

on a 5 speed car/truck is best you disable the fuel pump instead of the crank because if they push start the car it will turn on.


BTW thanks BOSS..:Handshake: also is there a way i can fix the title?

Can you elaborate on this? (the alarm controlled ignition interrupt) which wire/location exactly would I splice this relay in? somewhere under the hood? The signal from the AUX channel would have to be set to Latching type correct? Thanks!

[Eagle]

for the ignition you would use a 611T/
a Latch output on the alarm to trigger a standard relay/
or
http://www.the12volt.com/12voltimages/momentconstant.gif to use a momentary output from the alarm, convert to 12+ to then trigger a relay across the IGN wire, which ever one stops the fuel pump (my favorite becasue you cna easily trigger it from the remote)

I forget which ignition it was that the guys used to cut into, sorry. It was almost 4-5 years ago. It was under the dash though.

[sparg93]

do you guys have any photos of the wiring job you did??

I can turn a wrench, but unfortunately not very good and figuring out the electrics unless someone shows me :Wedgie:

[sparg93]

hey rigo - where do you splice the new fuse/switch in? (i'm a newbie with electronics)

Also, if i simply pull the fuse on the crank, is there a way someone could hot wire my hoe? (for a temporary solution)

[puckhead]

Very good posting here! Thanks for the write up guys! Will have to do this sometime

[TnTahoe]

my truck has something on mine but not sure what it is but when i turn it on and turn the key instead of cranking it blows my horn, it was on the truck when i bought it :)

[puckhead]

lol, that would be cool, if you hear your horn honking you know someones in your ride!

[yukonjacks]

On the smart start there is a trunk release. Is it possible to put an inline switch to the ignition? It would be an extra step to use the remote start, but it would be an excellent safety feature.

if they know theres a big chance they can start it. because they would know whats the kill switch for, and where to find it. but if you keep it to yourself they wouldn't know where to start. by removing the fuse the truck will not be able to crank even with you key in. so even if they brake your ignition switch and tried manually cranking it by touching the wires together the truck would not turn over. the only way to start the truck would be to push start or hot wire the starter when the ignition is on. but if they cant in the first try, thief will leave it and go look for something easier to get.

thats why i had so many hidden switches in my hondas.

i trust more the fuel pump fuse but thats located under the hood. i will try to get some pics of how to find the wire asap you're asking for.

btw i remembered my friend using a bigger louder alarm speaker under the hood and inside the car. i remember the one inside was so loud and annoying i felt like my ears where gonna pop.

not enough... u would here the horn run out side and see the back of you truck hauling ass. some people can even hear their alarm 10-20 foot away.

[puckhead]

Anyone know where a good place on line would be to get those fuse holders? The three stores we have that would have that dont.

Or would it just be as easy to splice into the harness? Is it hard to get to?

[thumper_ehhhhh]

Another good spot for the switch if it can handle it would be the rear wiper knob. Most of you have deleted the rear wiper anyway. Why not just use the knob for that puropse. Right out in the open nobody will suspect. Oh if your up here in Canada Canadian Tire has those fuse holders.

[cam3439]

Where's the fuse/wire used for the fuel pump on an '02 Tahoe? If it's under the hood, what is the fuse named?

[sparg93]

u can also get the fuse holders at radio shack.

I was playing around with the fuse panel ('99 Hoe), but i can't see an easy way to get to the wires...any recommendations?

[Dismay]

I feel like people are focusing too much on the fuse holder, If one of these is plugged in to the fuse panel, it will only draw attention. It makes much more sense to just splice into the wire in well hidden spot, and run the wires to your switch from there, leaving the oem fuse alone. You don't want to give the thief any clues as to what you have disabled.

True, i thought about that. Is it easy to get under the fuse panel to the wires?

[sparg93]

yeah...you definitely don't want to plug this into a fuse panel unless you have to...but how do you get to the wires behind the panel to splice them.

I've been playing around and i've had a really hard time finding the wire, let alone splicing into it.

[Slammedchevy01]

So is this controlled by the switch for it not to start or do u pull the fuse?

[Z-56 Hoe]

now isnt that an alarm right there?

[k gee]

Isn't this basically like a double kill switch for someone who has an alarm already? Just a hidden switch in case they find the actual alarm?

[cam3439]

pretty much

[k gee]

Thanks, I already have two kill switches. One is pretty much unbreakable.

[LazyAssLou]

Yea, I did this and my truck still got stolen. Damn theives!...

[TnTahoe]

I was looking under my dash the other day and found the source of my kill switch/horn thingy lol. It appears to be 3 relays wired to a bunch of stuff, but it disables the starter or something and instead of cranking the vehicle it just blows the horn everytime you turn the key when its activated

[Dismay]

That looks like a mess, lol!

[TnTahoe]

yeah i know

[rigo_jones]

Yea, I did this and my truck still got stolen. Damn theives!...

u serious? what did you disable? if you cut the power to the ecu or fuel pump there is no way the truck can be started. i find it hard to beleive it was stolen after u did this.


relays will do nothing for you and to me are pointless even the relays that your alarm came with are easy to disable.

i know i said i was gonna get pics but ive been super busy. i bought a house and i still moving in and setting everything up.

[MOBmentality]

My dude has a tilt sensor on his steering column somewhere under the hood.. and it doesnt matter if... the alarm is disabled.. and autostart has cranked the truck.. and the doors are unlocked.. but the key is not in the ignition.. and you move the steering wheel AT ALL.. it sends a pulse and kills the fuel pump, ignition and ecu... so the truck just sits there dead with the alarm screaming.. i thought that was kinda a neat deterrent...

putting the key in after its going off wont do anything.. you have to SET the alarm.. then disable it again.. then put the key in... so just cutting ignition wires wont do you any good.

He also has an old trunk latch key hole for the hood pop instead of a lever.. so you need a key to pop the hood... hes an installer and its his shop demo truck so he went overboard on alot of stuff.. but hes got some novel shit going on

[denalianyone]

Invest in a Mo Mo stering wheel with a quick release. Then whenever you get out the truck, the steering wheel comes with you.

[crmzendrgone]

When I first got my yukon I thought about doing that exact thing and running the switch some where like in the glove box or in a cigeretter lighter. I have seen that before. My cousin use to do car audio and he wire the gain on his amps to a false cigerette lighter so all you had to do was turn the cigerette lighter like a knob and bass no bass. That would be cool I have my radio hidden under the dash with a remote control and left the factory one in the dash. It would be cool and a good idea to wire one of the buttons on the radio and have that as the switch.

Not sure exactly how they started the truck, I was too sad to look. Seeing my truck like that at the impound. But it is getting worked on now so I guess I will never know.

[Dismay]

Tow truck? No amount of switches can stop that.

I've seen that done before. You can hook up a kill switch with a relay and have the relay triggered by the remote wire on the radio. Basically, the truck wont start unless you have the face on the radio and turn the radio on before you crank the truck. You also have to wire the radio to an ign wire instead of an accessory wire so the radio stay on during engine cranking. When its all done, its a pretty sweet setup.

[brassknucklemafia]

just make sure you dont hit the switch by accident and forget that its there..i did that while on a trip cross country. muysta sat at the gas station for 15 mins or more..felt dumb when i remembered..

[l.downen]

Need some help with this one. I'm "electrically retarded". I'm just going for the basic one rico originally posted. So all I need is a fuse holder and a toggle switch? Can someone post a link to each item I need. B/c all I can find is stuff that involves wiring, but I assumed it was plug-and-play?

[DenaliWhip]

My first night home with my truck some jackarse broke my window and all he got was a pack of smokes, next day I installed a Viper 2way alarm w/ remote start. I was gonna do it anyway but that fool rushed me into it.

This is what I was thinking of using ..getting rid of the key all together

[triniguy26]

ive done one better.pep boys sells a remote control switch for 20 bucks ,so you can either manually switch off the power to the starter or fuel pump or you can use the remote control,i prefer the remote control because you can really hide the switch and wires in a spot that no one would think of.I did it to my dodge ram and it worked great.they couldnt steal it.

[gfunkfb09]

What remote does pep boys sell? I can't find it anywhere online.

check this one out at amazon.com. and its a good price,you can wire it up to cut the power from starter,fuel pump,or even ignition,possibilities are endless.http://amzn.com/B000ZRXJY2

Thanks airrion i might look into that.
