With my battery in the trunk, I go even lower-tech with quick disconnect battery terminal clamps. Lift with a finger and releases the negative. I do this anytime I leave it out of my sight on the street. Also stops the magic smoke from escaping when you’re not standing by with an extinguisher.

I am pretty sure I have posted a photo of my setup but just in case here you go. Mine will see some track days and local rules call for an external cutoff, cable on lever runs up and over the top of the panel separating the interior and truck and has a 4” handle on the end. Quick pull and it’s switched off. Works great at car shows too. I stole the idea/ design from Rennsports 911 battery location kit.

Thanks, everyone, for sharing your ideas and set-ups. I'm going to mimic a couple of them and explore another method. If it works, I'll share it.

I have 2 kill switches. I have this one as my "main" kill switch. I also have another hidden kill switch as a backup. I'm actually more worried about my car getting towed away and not driven away.

I also always put a car cover on my car every time I park (if the car is out of sight). Obviously this isn't much security but at least it's one more obstacle for someone.

My favorite version of a kill switch is one that allows the would be thief to actually move the car out of its parking place, then die. A car sitting parked is not too visible but one sitting in an intersection, dead, is!

Add a time delay of some type to allow for 30 seconds or so of operation before the ignition quits.

As for the actual switch, if the thief is familiar with our cars, he will look for something out of the ordinary. I prefer to use something that you take with you & plug in when you want to drive. Consider adding a head phone jack near the radio that interrupts the ignition when nothing is plugged in. Plug in a plug with a jumper in it to complete the circuit.

Hide your spare fuses or take them with you, then pull fuses off the fuse box. Or pull the fuse from the ammeter circuit. Or pull the wires from the dash VR guage if you have a kill switch that allows the car to turn over but not start, then it looks like you are out of gas LOL.

1. Pop hood.
2. Remove distributor cap
3. Remove rotor and place in pocket
4. Reinstall distributor cap
5. Close hood.

You can solder a 14ga wire to the distributor side coil wire end , then run it to a well insulated switch hidden & grounded ...connected it will not run ...it may work just connected to the coil neg terminal

I did the same as Greg. Very simple to install a hidden switch that is still easy to access. Sure someone could bypass it if they pop the hood, but then they can also bring a flatbed and just truck the whole car away. You are just looking for a deterrent that is not a major pain to install or use.

I posted to this thread but i don't see it here.

I haven't done it yet, but I intend to add a circuit that would allow the car to start & run for 15-30 seconds. Nobody would pay attention to someone sitting in a parked car trying to gt it started. But if the car can be driven out of the parking place into a lane, then die, the thief will not take time to figure out what is wrong but just abandon the car. It will be within a block o you should be able to find it easily.

I even considered adding a smoke generator that wold come on when the engine dies. That would attract much more attention! That might make for a great alarm instead of letting the engine start in the first place.

Peace,
Pat
