Need A Kill Switch Wiring Schematic

[Eyegore]

Well after my sons truck got stolen it seemed that the consense was to have a kill switch and now that I have two c-10's I think I better wire them up so I have some chance at keeping them. So do any of you have a schematic for wiring a switch up? My mechanic said he has not installed one in years and me and wiring do not mix (ask my wife she was standing there last year when I grabbed hot 120, I did that after she said "wouldn't it be wise to shut off the power?") So I'm looking for something to give my mechanic for my 86 and my sons 80 to wire up.

Thanks

Tom

I can help ya out

What kind of kill switch are you looking at, keyed or toggle? And where are you planning on putting it?

[Eyegore]

Now a question for your question, what would you recommend - toggel or key? W/ a key are you refering to the type that has a hex pattern, I guess my trouble is that I don't think like a thief in which one would be more difficult - oh I'm not implying that you do though, I'm just having trouble figuring this thing out what will slow them down. I wish I could leave my great dane in the truck, nobody ever bothers her, she's taller and heavier than most people.
So Russel whatever you think would be the best.

Tom

Oh thank you!

[Russell]

I guess it depends on how anal you are...

By keyed, I mean that it is a switch that you stick a key into and turn like an ignition switch, whereas a toggle switch can be put most any other place...

As far as installing it is concerned, install it on the wire that goes to the HEI's power supply, but not in a place that is easily seen. This way he can break in, smash your column, and get the truck to turn over, but it won't ever start. This way the feller sits there for a couple extra seconds trying to get it to start (and it never will) which leaves some time for someone to catch him, and also keeps your truck safe. The theif won't try to find the toggle / keyed switch if he has any brains at all, but will take off and look for a new target.

Very easy install too -- Cut the HEI power line, install the switch between the two wires (you can add wire to it so you can put the switch wherever you want, like out back behind a fuel door or something) and your done.

Personally, I'll probally put a toggle in up inside of my dash, it will serve the same purpose, just that if the guy finds my switch, he'll be able to start it, while if you have the keyed switch installed, it will add further deterrant from him stealing the truck, if your really anal about it, you could weld the switch in so he can't bust it out and hotwire the keyed switch

Both installs would take the same amount of work (unless you wanna weld stuff, lol) and will do the same thing, just with different levels of deterrance. Just remember that none of these systems make it impossible to steal your truck, if he wants it bad enough, he'll get it, just that most of these guys don't have the tools or the time to bypass one of these switches.

I have put them in before were you had to have the turn signel on, plug in the cig lighter or something like that to make it start.

ok i have a toggle switch hiddle in my cab, i have about 4 other switches to various lights and such so he would have to know which one to flip. Tom, it you have a column mounted bright switch you could instal a floor mounted one that is wired at a kill switch. the power wire to the HEI that Russell is referring to i believe is Pink and the largest of the group of wires that goes into the distributor. You could also put a battery disconnect switch under your hood or hidden right behind the grille so you can reach in a flip it. Flaming river makes a decent switch but is rather expensive at about $50.

[Eyegore]

Thanks guys you given me plenty of ideas, Russel thanks for explaining witch wires. $50 seems rather expensive but one 20" tire on my sons truck ran $250 so in the end it could balance out. We are finally settling with the insurance company, and you guessed right - were taking a loss. We had reciepts for everything, appraisel, pictures sometimes you got to wonder if its worth fixing up a truck or car, because no matter what theft device you have - "if they want it bad enough......". Well my son is really putting alot of time into his 80, new front fenders, new cowl hood, solid skin w/ no indentation for the tailgate hopefully he'll get enough to finish everything up, so his next step will be kill switch, alarm.

[swervin ervin]

If you use a battery disconnect you'll have to reprogram the radio all the time. I think the simplest one to use would be to put a toggle switch on the HEI hot wire. Put the switch wherever you want and tell no one, even us. Make sure you put it somewhere it would be the least obvious to a thief but easy for you to get to. Wherever you put it, make the wiring going to it as invisible as you can. Anything out of the ordinary will stand a good chance of being spoted.

Not trying to disagree with you guys, but I go about things a bit different. I don't want the thug to think he has found the correct wires to even get the motor to turn over.

That's why I always use a relay and break one of the wires to the neutral safety switch. By doing it this way the motor will not turn over no matter what they do to the column.

My thoughts are it's bad enough to come out to a busted column. It's even worse to have a burned up starter and a dead battery.

Two ways to go on the key switch option. You can use an alarm style key switch, or you can use one from the rear door of a Burb/Blazer. They use a GM style key but have an electrical swith built in....

If you go with something like that isn't it easy to just cut and splice with wires with you being able to see where the key hole is then the connections is right behind there?

[Bowed]

I've been thinking about a switch set up to use when you have to leave your vehicle in a vundurable situation and you dont want to take a chance on some thief finding a kill switch if they had time to look for it . I was thinking of a switch that was in series with a carefuly placed fuse where if the switch was activated and someone tried to start the vehicle , the fuse would blow instantly and the ball game would be over right there. Maybe someone like Necromancer would have some tips on that .

It depends on where you mount it. If you mount it in a panel that has direct access to the rear, then it would be easy to defeat. If you mount in a panel that can't be accessed from the rear, it's as hard to defeat as any other key switch.



No matter what, it's still harder to defeat than a toggle switch....

[Eyegore]

Woe everyone wires, switches, access, there are sure are alot of great ideas but would it not be easier to get one of those column clamps that protect the internals of the column with heavy steel? I mean it seems that if your parked in a place where your truck will be left alone all day like in a parking garage, that is where mine will set it sure gives someone the oppurtunity and time to trace wires. By having the column protector seems that it would deter anyone since the cannot break the lock. Does this sound sensible? I know their going to get it if they really want it, a guy had his 92 c-10 stolen out of his driveway, they backed a wrecker up to it by slaming the lifts under the tires and just hauled it off alarm blarring and neighbor shooting at him, oh he also returned fire back. So I know nothing is an actual deterent just slows tem down. Just my two pennys.

i think i'm gonna add one of these tommorow when i wire up my tach

[Prerunner1982]

if you were to install an electric fuel pump you could also wire a kill switch to it, and one to your hei, and one to your nuetral kill switch. have to have them in the right sequence to start it. gives him 8 different sequences to choose from to get it right.

[Russell]

Just had an idea that would look completely stock, but serve the same function as any of the toggles or keyed setups...

Would only work for non-cruise trucks without the headlight / wiper switches in the truck.

Just need to buy a relay that acts as a bit of an electrical switch, so when you hit the cruise button, it opens the relay, and keeps the power flowing until you hit the button again, which closes the relay, and disables the vehicle.

What theif would ever think to hit the cruise switch if the truck wouldn't start? Also, if you forget to arm the system and he decides to set the truck to cruise control, it would die, and not start back up unless he thought to hit the cruise again, lol!

I mean, its totally stock, and would look completely factory if you did a proper job wiring it.

Too bad we have to worry about this stuff.

I have toggle kill switch and Grant detachable steering wheel.
