Easiest Kill switch

i wouldn't wire it to the starter. that's way too easy to bypass, one long screwdriver to short the terminals and done. you're better off hooking it into the ignition coil power circuit.

Bypassing the ignition is just as easy.
 
The key is to have more than just one device that you disable on the car. The longer they have to mess with it to try and get it started, the more likely they'll just move on.

A few of my plans are an ignition kill switch, a fuel pump kill switch, gps tracker, etc. Or, if you have an EFI engine, just pull the computer if you have to leave the car. 😉

Used a piece of thick black vacuum line with "correct" ends glued on.
Or snip a length of wire with the correct end on it from the junkyard, then tape the wire into the loom to make it look original 🙂

If you can get easy access to the starter... with headers the only reasonable way to get to mine is to crawl under the car, which is lowered, so you better have something long that won't make contact with a ground anywhere. Also, if they already have an extra HEI +12v plug (or even a regular spade plug, that's all it is) with a good length of wire, all they'd have to do is plug it into the distributor...

My '81 was almost stolen a couple years ago. I only had the coil unplugged that time, but it was enough to keep the scumbag from getting the car.

I'll have several deterrents in mine. Planning to weld/bolt a plate in over the lock cylinder so you can't jimmy it as easily to unlock the door. I currently have a secondary siren in the interior of the car that you can't get to without removing stuff (doesn't go off until they turn on the ignition). At least two separate, hidden kill circuits in addition to the alarm system itself (using original switches, i.e. headlight switch, horn button, power window/lock button, etc.) will be put in place so they can't start it. Since I'll be rewiring the car eventually, all this wiring will be taped and tied up under the dash so they'll never know what's what without a flashlight and following wires closely.
 
If you have an electric fuel pump, simply take the fuse out & carry it with you. You did install a fuse in an electrical circuit, right?

I don't know if thieves carry spare fuses with them, but this is one more way to hamper their efforts.
 
If you are running an MSD 6 series ignition box, just follow their directions and wire up a kill switch that way.

Yep, actually all of the fuses for the EFI run through a relay board in the engine bay.

For my kill switches I plan to run an actual keyed switch instead of a toggle. That way if they do find the switch they'd still need a key to engage it or start ripping things apart to get to the backside of the switch.
 
Thing is (if the wiring behind the switch is somewhat accessible) is they could clamp one of those no-strip wire taps on and bypass it. A dummy switch or two isn't a bad idea either 😀

Ground the tach terminal on the cap it's the terminal next to the power input to the coil. Use a 20 gauge wire and run it to your toggle switch, from there to a good ground. If you can find a factory connector end it looks like it came that way.
Be sure to hide the switch well, mine has saved my car three times.They might break the column open but the car won't start,and there won't be any relays or bogus looking wiring to get ripped out from under the dash.
