Immobilizer: Circuit Breaker, anyone?

[Padawan]

My Challenger is on the trailer on the way to her new home, and one of the things I've been thinking about is theft. I have a garage spot in a condo garage, all the way at the back, the guy trailering her out of there actually deserves to have the car. 

So stealing from the garage is not my worries, but still I've been thinking about a circuit breaker, in case I need to park it somewhere. There are a few professional ones, like Ravelco, which costs about half a mille to have it installed. And I found this very cool DIY immobilizer: http://autospeed.com/A_107975/cms/article.html
I am not qualified to do the DIY one without help, but I really like the concept. Does anybody here have something like this, Ravelco, other or the DIY one, installed in their cars? Or am I too paranoid anyway?

For less than $20 one of these well placed would be just as if not more effective IMO & a whole lit simpler.

I beat an immobilizer in under 2 minutes , you just need to hide a switch to ground the - coil wire so it will not fire , if you have a tach you can connect to that wire under dash so nothing appears unusual

Where you live isn't quite Boston but is pretty close.  Always good insurance to get something.

On my other old cars I used to pull out the coil wire. 

I used to also have multiple switches hidden in the car to break the coil wire connection.

I think there is a thread on something like this, maybe....

Get somthing that makes noise.  Thieves run when they know attention is being drawn to them.  A guy I knew that set up a system for a friend had 2 sirens, one under the hood for people to hear then 1 under the dash, tucked up in side the dash so the thief couldn't tolerate the noise. 

There's a place across from the Super 88 market that does stereos.  They do alarms as well.  They do high end cars like Porches and such.  Might be a good place to get info.

My cousin's husband has a really nice Grand National.  He uses a toggle switch to cut power to the fuel pump when it's parked.

Thanks for all the tips! Will look into switches for the coil wire. The driver just called and will be late 2 days, argh.

@SuperBlue, do you mean "Sound in Motion" at Allston Auto Tops? Could be a good place, on Google Maps there seems to be an old Muscle Car (orange with black viper stripes) in the lot (only in that 45 degree view, here: ). Good sign.

[Super Blue 72]

Yup, that's the place.  Never seen any muscle cars in the shop but lots of European stuff, Porsches, Audis, mercedes, etc... I don't know how good their work is but it seems to be always busy and they have decent customer cars.

In the late 70's in Hotrod Magazine, one reader wrote in and said he uses the two rubber ends from an old coil ignition wire and then replaces the used coil wire with a piece of hollow vacuum tubing. No voltage or current to the distributor, hence the engine will never start.

[Super Blue 72]

Silly story related to this.

When I was a teen, I had '67 Olds Cutlass.  I tried to start it one day, wouldn't start and this car was flawless starting up every day.  Looked at the fuel delivery, check the wires for spark, all the basics but after a while I was like  still.

Duh, I forgot to flip the kill switch.  Started right up after I did that....

You remember that from a 30+ years old magazine? My deepest respect.  If that's your Challenger in your Avatar then mine is its twin brother!

That is exactly what I want! Haha, nice. So either a kill switch to kill the ignition coil or a battery master key should do a good job. I found the 27 pages Dart & Challenger wiring diagrams, if in the end the car changes radio channels when when I turn on the wipers I'll call it a success! 

[Chryco Psycho]

I have always grounded the - coil wire , this way no matter what they jump for power , hot wiring the coil & shorting the start relay it is never going to start unless they trace the wiring back under dash

[Super Blue 72]

One trick I was going to do in the Cutlass but didn't get to install it was to use the cigarette lighter as one of the switches.  I would have a flip switch inline but also in addition the cigarette light would act as a momentary push switch. 

Would have to contort your arms to turn the key though.  Maybe that's why I never installed it...

I carry lots of insurance.  Get a big fat check if someone steals it...

If you are really nervous;



I'll leave it up to you on what to do with it, someone better bring a flatbed.

That's my way of thinking too. I like Goody's idea for long term storage.
