You need to cut the WHITE/ pink wire in your ignition switch harness. Connect one cut side to terminal #30 on a relay and the other cut side to terminal #87a. Connect terminal #85 to a good ground and terminal #86 to a hidden kill switch. Connect the other side of the switch to the RED / light green wire in the ignition harness. Place a 5 amp fuse inline on this last wire within a few inches of the RED / light green wire for safety. Hide the switch well and use it to immobolize the car.

can't you also just simply cut the ignition wire and put in a two way switch?

most single throw toggle switches aren't rated for that amount of current....dont be cheap, spend 4 bucks and buy a relay and socket

One suggestion. Do a fuel pump kill. The starter relay is easy to access on your vehicle and will only take 10 seconds and a screw driver to get past.

Fuel pump kill is also just as easy to bypass. Put the starter kill relay under the hood on a Ford and it will be hard to find.
