Where are you trying to stop the thieves? A thief can open the hood of a '65 Mustang and run a jumper wire from the battery to the coil and use a screwdriver to activate the starter.
Your best bet is most likely to put an electric fuel shutoff solenoid in the fuel line with a hidden switch to turn it On/Off. Even if a thief hot wires your car and gets it started it will die as soon as the carb float bowl goes dry. He may get a couple of blocks down the road before it dies and at that point he will probably jump out of the car and run away leaving the car undamaged.

plus 1 on fuel shut off
Or take coil wire or rotor every time you need to have secure.

 

Done that many times .

 

How It Works - Z-Lok HoodLock

 

Switched ground to negative side of coil. Very simple and effective. You can even tie it into the tach (in the car) so it's not an obvious extra wire connected to coil. Not too many thieves will try and troubleshoot no start while jumpered.

 

Any thief smart enough to hot wire the coil under the hood is going to spot the extra wire. He's also going to have a rotor and coil wire in his pocket.

 

Hoodlocks work well for midgets with short arms. In the real world a guy that knows what he's doing can reach up from underneath the car (Ford) and connect a jumper from bat to I term on the sol. A simple twist of the alligator clip to S and it's running. No need to add hoodlocks or fuel cutoff solenoids. Ground the coil and the car won't run. Period. You can even get creative if you want. Ground the coil through the interior light door switch. With a bypass of course. Thief pops the hood, jumpers, and car is running. He opens the door, it dies, repeat repeat. Keep it simple.

 

Z-Loc combines the hood lock with a short to ground of the ignition primary.

 

Kinda like a simple throw switch without the hoorah?

 

Got a cut-off switch on my battery. Turn the switch and no power to jump with.

PS...............battery is in trunk.
If they want it bad enough NOTHING will stop'em. Repo man truck....back up to rear of car....lift rear tires and drive off. Never getting out of truck.

 

I usually just take the rotor out, most idiots don't even think to look under the distributor cap. Not like the coil wire is a bad idea, but somebody happens to look at it quickly they may return if it's parked awhile.

 

I keep my Mustang in my garage. It has been stolen in 25 years

 

a chipped key ignition. it might be possible to adapt one to an early mustang

 

I don't suggest the coil wire. if I popped the hood and wanted your car I would use one of the spark plug wires. it will run good enough on 7 cylinders for me to take it.

 

yep !

 

Dont hide your armor. Steering wheel lock (ie The Club, etc) or steering wheel to brake pedal lock bar. Simple, effective, and very visible. Most thieves will take one look and move on to easier prey.

I'm all about multiple layers of protection and the club is one of them but all it takes is cutting the steering wheel and the club is off. Now, pair that with a few other layers and soon it becomes way too much trouble to grab the car.

 

Take the transmission with you every time you leave the car. Even if they get the engine started, they can't get far.
Lol

Wondered when that was going to be posted!

Cracks me up.

I would vote for the coil wire if you don't have an electric fuel pump.

Personally, I have an ignition kill switch. It's not real difficult to defeat but it does do its job as far as dissuading opportunistic theft, which is the point.

I built a hood lock custom for my car and it has a security system so I am not too worried about it My biggest concern is now what might happen if I break the lock one day... because I engineered it to be nigh undefeatable!

 

Kelly, you should have also engineered it to be up breakable. >

 

I always felt a fuel cut, either switch or valve is one of the best ways.
Reason being, thief gets in, starts car (because some fuel in lines and carb) pulls out form where it's sitting, it DIES because of no fuel. Depending on where this happens of coarse (no magical answer for everyone), the car dead where it sits may now draw unwanted attention. What thief is gonna then hang around because they're caught off guard. Different locations you're in, different solutions may or not work. Which is what AWHTX also said, +1.

 

Sorry for the long response but I work two jobs... one of which is a police dispatcher and vehicle thefts happen everyday and 90% of the time to cars much newer and with much more advanced ignition and alarm systems on them etc. It seems to me the most popular vehicle that I see stolen would be a 1990's Honda Civic/Accord or something of a similar year. Anyway, I think that if one was relatively smart and really wanted to steal any of these older cars that they wouldn't have a too terribly difficult time in doing so. If one had a trailer and a buddy to help him out all they'd have to do is break into the car, put it in neutral and push the car onto the trailer or tow it behind another vehicle with a tow strap, especially since these cars aren't very heavy. If the owner of the vehicle wasn't home or was sleeping at the time and didn't have a home/vehicle security system or have nosey neighbors, their car could be long gone in a matter of a few minutes.
