I bought one of those clubs you put on the brake or clutch pedal. so brake in my case. Do you think a fuel cutoff valve in the trunk is a good idea or will people see me going in my trunk all the time and figure it out? what about putting it on a remote controlled solenoid?
 
what you need is a system of things, hidden switches, line loc for the rear brakes, fuel cut off. removing the coil wire doesnt really help these days as thiefs either carry one with them, or make use of a plug wire and just run on 7 cylinders.

if you use hidden switches, you will need at least 3 of them. remember that where you hide the switches, thiefs have likely already looked. if you use three of them you can deter them to the point where they are taking too much time to get the car going, and move on to a different and easier target.

i forget who, but there is a company that makes a line lock for the rear brakes. you install it in the rear line, and when you park the car you hold the brake pedal down and lock the rear brakes in place.

you can still use a fuel cut off switch, but use one that is activated electrically, and put it on its own circuit. that way you can hide the switch. again you might use at least two switches to activate it.

you might also use a seperate switch to activate the starter instead of using the ignition switch.
 
I've seen the battery shutoff's installed inline with the chassis ground cable, out of sight, near the motor mount. Also seen people remove their shift knob, as long as it's push button, it's a pain in the rear to get in gear.
If you have an electric fuel pump, the shut off is an idea, but it may be better to try to disable to ignition system, or both at the same time.

Just some ideas

Remove the coil wire, and she ain't moving.

basically the way these cars are stolen is a thief putting a wire lead from the 12v battery terminal to the + side of the coil, then jumping the solenoid to start the car, and he's gone. So that wouldn't do anything.

You have to find ways to make the car take longer to steal which would visually deter thiefs to move onto another target. The brake pedal club you have is good, but I'm too lazy to use that.

I like having a systematic way of cutting out the power to the electric fuel pump that only you would know how to do.
 
i like the electric fence hooked to the drivers seat idea.

one idea i had was to isolate the starer solonoid from ground via rubber etc. and hooking your horn switch to the solonoid for a ground, one downside though your horn dont work with the steering wheel.

something that would work too is to have an msd box with a remote rev limiter chip for 700rpm with a high stall converter.

On the same idea they make a battery disconnect that mounts on the battery's negative post, but if you remove the big green knob it would be hard to jump across it w/o having a heavy gage wire in hand or a spare green knob.

This is not a good idea. The solenoid runs off battery power and will drain it. Line locks are for smokey burnouts, which last seconds. Leaving the line lock on too long will fry the solenoid. But, they can be good for passing a safety check for those states that need them if your e-brake doesn't work. Find a shop that lets you stay in the car. They'll have you pull the ebrake and at that moment set the line lock. viola!
 
where can you buy these switches and cutoffs and such that you keep talking about? or does anyone have a write-up of how to install these? i'm not the most talented electrical kid on the block.
 
What if you lock the hood.

Under the hood, put a remote controlled alarm system. Most of these systems have a power on/off terminal. Connect this terminal to the coil.

If the alarm is set, then no power to the coil. Deactive the alarm and everythings good.

I'm also putting the battery & solenoid in the trunk. That way they would have to supply their own hot lead. (assuming they got into the engine compartment)


What do ya think?

Right on Lman! I'm thinking about getting some tiny stickers made to put in the vent windows that say "This vehicle protected by Smith&Wesson" :D Besides, if I shared my anti-theft "secrets" here, any idiot gooling could find them and know how to steal MY car :(

i heard of an idea that involved the cigarette lighter, you need to push it in for the car to start, but i dont remember the specifics......coil wire, starter switch, or something....
