for truck safety I like to put a switch on the coil power wire. Don't matter if they bust the ignition lock, its not going to start. As for the tires /forums/images/graemlins/dunno.gif

Not the coil power wire. You better use some thick gauge wire if you wanted to do it that way, because you're going to be adding several feet in wire before it gets to your coil now= more resistance and voltage drop. no bueno.
The negative side of your coil will go to your tach. If you disconnected it from going to your tach and grounded it out when you left, your engine will crank but have no spark.
I was thinking about also doing a switch hidden somewhere on the rear of the vehicle so you can get out and click that switch opening the ground for your electric fuel pump.
I also have an alarm. you can hook up a starter kill with the alarm.
I also have a club, when i park my truck for a while somewhere unattended..
So lets see here, 1. club 2. alarm. 3. starter kill. 4. ignition kill. 5. fuel pump kill.
the more things you throw at those potential thiefs, the longer they'll be there for a while trying to diagnose how to get your vechicle started.. if they get it hotwired to crank, they'll have to figure out why its getting no fuel or spark... /forums/images/graemlins/thinking.gif
