Why not a good old fashioned Fuel line shut off valve, say behind the seat, Valve outside under cab, lever inside?

 

I think a lever might be too obvious. I'm going for stealth in this case.

 

I know killing the fuel pump will do the same thing, but if you don't have an electric pump just install an early style fuel tank switching valve. They are electrically controlled but don't pull power except when actually changing from one tank to the other. Here are several scenarios:

• If you had dual tanks but don't use both, just seal off the line from the tank you aren't using and flip the switch on the dash to that tank when you want to prevent it from being driven.
• Ditto above but use an alarm system to treat the valve as a door lock and turn the valve to the non-existent tank with the alarm on. Automagically it will go back to the existing tank when you unlock.
• If you still use both tanks you can still add another valve, just install it between the existing valve and the engine, and cap one inlet off. And put a hidden switch somewhere to control it.

 

I have dual tanks on it now, but I will be using both so I don't want to fill one up and have the other sit empty. Plus I don't want the theif to spend enough time in the cab to eventually start looking around and figure out where the switch is.

I like the idea of having it at the bottom of the door, but A. I don't know how i'll keep water or moisture away from it and all the wires without ruining it, and B. there will be a fair amount of wires in the door already and IF someone was watching me hop out of the truck, they would see me flip the switch. So that leaves me with mounting it under the seat.

 

It's a problem balancing a position that's within reach of the drivers seat, with being hidden or hiding in plain sight. Over the years many different things have been tried and the best one I've seen was converting the cigarette lighter into a momentary push switch in series with the start wiring. So you had to hold the lighter in whilst turning the key to crank the engine.

You can also get creative with hidden proximity switches behind trim, the sky's the limit - good luck

 

Goto to post #50 here for the revenge!

Oh man I love dogs. I think I would've kicked the S outta him just for the hell of it. I swear people have no common sense or decency, and S-heads like that need to be taught a very valuable lesson....like what life is like in a wheel-chair.

 

Ahh, ok so something like a solenoid driven slide bolt through the bonnet catch, or a mag-lock holding the bonnet itself shut. Activated by an alarm or central locking system.

For an alarm system, swap the external siren ( nobody pays attention to them anyhow) for a high intensity piezo screamer inside the cab. Makes it very uncomfortable to hang around in there trying to complete the theft.

 

Good ole Florida summer time sun cooked him really good! As he did not roll down any windows the temps were OVER 130deg F!!!! I let him out due to I did not want to deal with a dead cooked crook on my hands in the car but had fun taunting him with the Rex and my dogs!

 

Lol.

Ya know, he could've died and then you just pretend you got home late and not know anything about it. One less f'r off the planet.

 

Just don't put up the yellow and black sticker on the dash saying

"Super sneaky secret fuel shut off valve located behind the seat"

It should be fine.

 

Ahhh, darn. That's what I was planning on doing.

 

I have installed Kill switches on most of the vehicles I have owned . I sold one to my little brother years ago . After 3 days at a shop ( he lived over 100 miles away ) he called for advice . While on a date ,someone's foot found the kill switch ! The mechanic could not figure out why the coil was not firing ! I told them where the switch was located . Easy to get at , hard to find ..... I run a bit of wiring ,looks factory , and isolate the coil . I know it works ! Around the e brake area on my 78 with a small push pull switch .

 

Do you have any pictures of the work you did? Or where the switch was located at?

 

Some greasy part lying on rags on the driver's seat with a note on the dash reading, "Gone for parts, back soon".
