Anti-theft Kill Switch

[intocarss]

If you have a MSD their install instructions say you can put (depending on how it is hooked to your distributor) a toggle switch on the white or violet wire. I did it and hid the toggle..When toggle is off car will crank but won't start

My car also came with a wire running from a momentery switch through a relay to the back of the start position on my Ign and you have to hold the momentery switch for it to even crank . Hope it helps
