kill switch

i want to install a kill switch in my 96 mustang so that the car wont start and so that when the switch is hit the the engion is killed...i need to know what wires to cut and reroute to do this and where these wires are located...a diagram would be very helpful if one is avable.

In the ignition harness there is a WHITE/ pink wirethat is your starter wire. Now follow this link: https://www.the12volt.com/relays/page2.aspCruisin Security And Sounds

i was looking for an easy way to install a kill switch in my car without cutting wires since i didnt really know what wires to cut so what i did was i reffered to my owners manual and found the fuse that controls the ignition and the starter and replaced that with two wires stuck into the fuse socket and i ran it to a switch inside my car and it works like a charm. tha car cant be started without this switch being enabled. its an easy way to install a kill switch without it having to be permenent.

But you just removed the fuse? Now whatever was protected with that fuse is now unprotected....doesn't sound like a good idea to me.Q: What's the best nation in the world?

I always just use a rocker switch and interrupt the starter wire...Cut it in half, wire each end to the switch (you will have to get some extra hook-up wire of the same guage as the starter wire to make it longer so you can route it to the switch), either gives continuity or not...simple but extremely effective. I like rocker switches cuz u can get em full black in color and they don't stick out which makes em easy to hide. The wire you need is White w/Pink tracer in the Ignition Switch Harness, just take the steering column cover off and you'll see those heavy gauge wires coming off the key.

I was thinking about doing the same on an old MX3, what size switch (amp rating) is needed?

I believe it's a 30 amp switch, I get em from a local auto parts store, i'll check it out. Checked, it's a 32 Amp switch.
