All I did was break the + side of the coil circuit with a small heavy duty toggle switch..
Mounted on the firewall by the heater box on the passengers side..You can't see it from the drivers seat.
I have to walk around to the passengers side to activate it..
I only use it when in the city.
Never enough time to do a job right...but always time to do it over...
I have a lock cylinder from an old security system (or so i'm told) on the body of the jeep near the drivers door hinges but I'm thinking about using it as a cut off to the fuel pump that way it cant be pop started. Also I've heard of people doing something with the cigarette light but I dont know of your CJ has that "luxury" haha.
Cut off switch hidden somewhere is best bet, but the lock is another good idea, trouble is that a real pro, will have it regardless. All you can do is just make it more difficult or make the thief take more time to steal it than is reasonable. A security system is also a damned good idea, you can have one installed or do it yourself, many on the market to choose from. At a minimum, put a hood latch lock on it, that way, your battery won't end up in some illegal aliens boat or truck. Lost mine years ago for failing to have a hood lock, expensive lesson.
