Vehicle theft is a big problem, but traditional equipment like alarms and steering wheel locks don't always seem to cut the mustard. A sneaky way to get around a car getting stolen is installing a starter kill switch. This literally stops the flow of power from the battery to the starter, and can be operated with a switch. You'll have to flip a switch and turn the ignition to start your car, but that's easier to deal with than getting a car stolen.
Pop the hood and find a location to mount the Ford starter solenoid. This will most likely be on the fender well. Secure the solenoid to the sheet metal using the drill and self-tapping screws.
Follow the wiring that goes from the battery to the starter motor. Unbolt the battery cable from the starter using the open-end wrench set and the run a length of cable from the "B" terminal of the solenoid to the starter motor connection. Strip 1/2 inch of shielding from both ends of the wire and crimp a battery terminal onto the ends using a terminal crimper. Then bolt the cable to the "B" terminal on the solenoid and the starter motor using the open-end wrench set.
Run a section of cable from the positive battery terminal to the "A" terminal on the solenoid. Strip 1/2 inch of shielding from both ends of the wire and crimp a battery terminal onto the ends using a terminal crimper. Then bolt the cable to the "A" terminal on the solenoid and the positive terminal on the battery using the open-end wrench set.
Mount the on/off switch to the dashboard using the open-end wrench set. Run one color of the 18-gauge wire from the "A" terminal on the solenoid through the firewall of the vehicle to the switch. Run the other color of the 18-gauge wire from the "I" terminal on the solenoid through the firewall of the vehicle to the switch. Strip 1/4 inch of shielding from the end of the wires using the wire strippers and crimp a blue ring terminal on each end using the wire crimpers. Secure one wire to the "A" terminal on the solenoid and one to the "I" terminal on the solenoid using the open-end wrench set.
Connect the wire that comes from the "A" terminal to the center prong on the switch using the Phillips-head screwdriver. Then connect the wire that comes from the "I" terminal to the top prong on the switch using the Phillips-head screwdriver.
Turn off the switch and try to start the engine. It should not turn over at all. Then turn on the switch and try to start the vehicle, and it should start promptly.
