I dread leaving mine parked anywhere.
The opportunist look for the easier car to obtain. The professional shopper want a parts car.
A good GPS alarm alert system could be a benefit.

A steering wheel club with the wheels in full turn lock helps deter a tow truck, but these cars are so light dragging them from the front with the hand brake on isn’t much deterrent.
We can put all sorts of wheel U-locks thru the Fuchs but consider the damage that it would do if an evil entity tries to drive or pull a car w/these on. This is done on motorcycles.

As Dennis (timmy2) explained, the kill switch needs to ground FP relay pin 85 on a CIS car. That means it is kill function that completes a circuit, as opposed to most other kill switch that usually open a circuit in order to stop current flow.

So whatever switch you choose for this purpose, make sure it can remain with its contacts closed when you want the car to not start. Headlamp washer switch may not be a good candidate for this, because it is a push and release switch. It has contacts that close only when you push the switch and open again when you release it.

I have taken a few precautions including a quick release wheel, fuel pump cutoff, inertia switch etc. but in most cases they could still tow it away given the opportunity.

Back in the 90s I was in Caracas on vacation (I was born there), staying with family friends. They had a then-new 80-series Land Cruiser. It had an alarm, a kill switch, a steering wheel lock and also a padlock over the shift lever, bolted to the tunnel. Their previous one had all the same, and was taken off the street in the middle of the day while shopping. Tow truck's gonna get you, but all of the above will handle at least 80% of the risk.

I just found a simple switch to disconnect the ground to the coil. Basic, hidden, useful.
Extremely annoying to find when trying to revive a car….but it does work

Sounds good. How does this work. What connects up to what?

Well, I suppose you can hook it up either way.
The one I found has been removed….
The coil needs power to start, 12vdc
Re-route that positive lead to a switch, run an identical color wire from the switch to the coil.
Switch on, coil has 12vdc
Switch off, no power to coil, no spark.

Figure on 15 amps, maybe 20 for the switch (old wiring has increased resistance)

The ground switch I found comes from the negative side of the coil and goes to the distributor.
It was all hidden inside the wiring harness, nice and tricky.
Same principle, run the ground up to the switch, same color from switch to distributor….

The key is making it all look stock.
Hide the switch very well so I cannot see any switch when I look underneath the dashboard….because there should never be a switch under there.

The older unit, which he was very proud of, used an old high beam foot switch.

It’s all gone now….because this is now a Sunday show car at 50 years old.

Good idea Rich. That certainly makes the car undriveable - thanks.

Aftermarket remote door opener/starter. Wire starter to disable fuel pump. All from your iPhone. Systems like Viper also provide GPS.

Here's a nice schematic where if you don't switch the killswitch properly on before turning the key, the horn will wake up everybody around.



"Heizung zur Benzinpumpe" means the wire/current coming from the fuse panel to the fuel pump.
"Kippschalter" is killswitch
"Hupenrelais" is horn relay

Unfortunately the horn or any alarm might wake some people but i very doubt they will do anything about it..At least in CA people don`t...;-)

No car is impossible to steal. The trick is to make it harder to steal than the one down the block. But if your car has been chosen by a real pro, there is not a lot you can do to keep it.

Years ago, there was a BMW dealer near where I live that kept having cars disappear from their lot overnight. A cop finally caught the thieves in the act. The thieves got a brick truck with the hoist on it. They would pull up in the alley behind the dealership. One guy would go rattle the fences at the front to distract the dogs. The another guy would ride the crane over the fence, put straps around the car they wanted and they would just lift it up and over the fence. They setup a facade of fake bricks around the perimeter of the truck bed to hide the stolen car. The only reason they were caught is a local cop turned down the alley while the stolen car was flying over the fence.

For my cars, I have a defense in depth approach. There is a switch that kills the ignition circuit. I also have a GPS tracker module for luggage tracking that has an internal battery, and is wired into the car's battery to keep the tracker charged. It can be tracked worldwide. So if my car disappears, I will be on my phone finding it. I helped a co-worker years ago by doing the same thing on his 67 Mustand fastback. We put a cell phone on it with a "mommy tracker" program that would tell you where it was. When his car disappeared, we got on and found it's location, and drove there to steal it back.

My all time favorite was a guy who wired the seat in the car to an ignition coil, and fired it with the same pulse as the ignition circuit. He had a remote key fob to disarm it in case he forgot. But if you didn't disarm it, the engine would start right up, and you would be getting spark plug voltage into your rectum. It would stop if you didn't touch anything in the car, like the door release handle, the key, the pedals, the steering wheel, or the shifter. He came out one day to find a guy just sitting in the car with it idling. The thief wouldn't touch anything for fear of getting shocked. The cops locked him up for auto theft.

Yes, but the thief himself won't like it, I promise.
And on every try he will hate it more and more, ... that's why it makes sense. :-)

Andrew people are generally scared to do anything about honking cars...it is everywhere..the sound really means nada...for a thief who know some kind of horn is no way any distraction..look here 2 thief are stealing FERRARI in day time..here using slide hammer..that why my 911 lockshield protects the ignition so the slide hammer does not remove the tumbler..

Years ago when they started putting the high beam switch on the turn stalk we used to install a kill switch using a floor mounted high beam switch. When you leave the car you press the switch with your foot and it kills the ignition when you want to start it you click it again and start the car. Nothing better then hiding in plain sight

Long time ago I had a 924 Turbo that had a faulty ground between engine block and body. Because of this, once in a while, it wouldn't crank. Only a small click and nothing else happened. I would then just start it by temporarily connecting a jump start cable between battery negative and engine block. That fault was kind enough to occur the night I parked the car in a street in Paris. But the bastards ruined almost everything under the dash and on the central console, trying to find a kill switch that didn't exist.

At least the car was saved. IMO whatever will delay or prevent a thief from doing what he wants to do, whether a honk, kill switch, electric shock etc. is worth implementing.

So Ivan, how do you prevent your lockshield from being unscrewed? How is it attached? And do you still sell it for 80 euros plus shipping? I think I might pull the trigger.

well..the design does not allow you to grab it..that is all i would say here.;-)
The hole is small enough for the key but the tumbler cannot be removed..
I sell them on French forum .just renewed the add..
