Hi..Has anyone heard of an immoblizer that prevents you from turning car on without putting seat belt on? Anyone knows the name of company that makes it? Anyone has it installed on their car?

 

Shouldn't be too difficult to make your own. There is a sensor hooked up to the drivers side seat belt. Just wire it so that when the seat belt is connected, the fuel pump power is connected. Get a wiring diagram from a service manual.

 

See the red link in the upper right hand corner??

click that..

check the audio video security section...

all it is is a relay, and some wires..

have fun searching ^^

 

The reason I'm asking is because I had a dealer install a new recalled ignition switch and when they opened it they said they saw wires going from igniton switch to some piece attached to to ignition which they said it was an immobilizer.. The wires they showed me were not connected professionally by the person who I bought the car from and the dealer said they have to remove the immoblizer circuit in order to put the new igniton switch. They said it's better not to have the immoblizer circuit off then to have it on because it could cause sparks and set the car on fire..Is this true. Can sparks from ignition set a car on fire? Also, if you have this seat belt immoblizer circuit, can thieves still steal the car through breaking igniton and hot wiring?

Sparks and improper connections can cause fires.

It is normally not a good idea to setup your immobilizer circuit around the ignition switch, not cause it can cause fires, but because it makes it easier to hot wire the car.

The most effective immobilizer circuit is to cut the fuel supply to the engine.

There are many ways of doing this electronically.

One easy way is to cut the power to the fuel pump, another is to cut the ground to the injectors.

Cutting power to the starter is not enough, because you can easily push star the car.

 

Do you know any good quality, cheap immobilizers that cut the fuel system? Are they hard to install?

Quality completely depends on the install, and the relays used.

Cheap? Automotive relays run around USD 0.50 to USD 1.50, then some 20 AWG to 16 AWG is a few cents a foot, a soldering iron can cost you USD 5.00 to an insane amount, solder is cheap, some good eletrical tape (3M Tartan) is another 50cents. You can go cheap on the relays, but i suggest you use BOSCH relays.

please read the audio/video/security forum... then check out The 12 Volt to read about car security, and relays.
