hello,
Just wondered if anyone has used a kill switch in there car? i would like to install one but not sure on the loaction it should go? i no it has to go where power is applied, but is there an easy way to install it?
Thanks in advance!!!

Depends on what kind of car, what type of ignition system and what it is to be used for I'd say.
Doesn't necessarily have to be in a hot wire, a ground can be used for a kill switch in some cases.

oh sorry, its a 1972 chevelle, 350 HEI. i want the kill switch for theft purposes. any ideas?

For preventing amatures from joy riding, just hide a switch up under the dash or seat that interupts the +12V to the HEI. Of course all they need is to jump from the battery to HEI with their own wire...... Another method is a solenoid in the fuel line or relay to power electric pump with a hidden switch. Depending on carb, they get a mile or so and it dies. You can also change the START circuit to use a hidden momentary switch (behind a kickpanel for instance) to activate the starter. Even with the key, you'd have to know where it was. Pros will use a rollback or wrecker anyway, so nothing prevents that except a garage with alarm.
