Anti Theft Switch For Your Binder

By Doc Stewart

Here is a variation on the old hot rod ignition cut off switch.

With this switch activated, the engine will turn over but it won’t start. If the thief is smart enough to run a hot wire to the coil, it will start but will run out of gas in about 200 feet!

Parts needed:
IH fuel selector valve, cable and integral fuel gauge switch. Find them in 67 and later trucks with dual tanks.
1/8 brass pipe plug
#14 twelve-volt wire & misc. wire connectors

A. Modify the selector valve by removing one of the outlet pipes and replacing it with the brass plug. I set it up so the pipe was plugged when the cable knob was pushed in.

B. Mount the selector valve near the fuel tank and run the cable to a suitable mounting place under the dash or hidden under the seat. Interrupt the fuel line and plumb it to the selector valve. By pushing the knob in, the fuel is shut off.

C. Interrupt the wire from the ignition switch to the coil. Run a new wire from the ignition switch to the center terminal of the gauge selector switch on the fuel valve ( by the knob). Run a wire from either end terminal of the gauge selector switch back to the coil wire. Now, when the gauge selector switch is turned one way, the ignition can be turned on in the usual manner by the ignition key.

D. Run a second wire from the other end terminal of the gauge selector switch to a ground. Now, if the gauge selector switch is turned that way, the ignition shorts out if the key is turned, the ignition is jumped or the coil is hot wired!

E. For safety’s sake, install a fifteen-amp fuse in the new wire from ignition to the gauge selector switch. Now, even if the thief figures out your switch, it won’t work because your hidden fuse is blown!

Tips: I mounted the cable knob recessed under the dash just enough so that when it is pulled to the out position, the knob can be seen at the bottom edge of the dash. This is the normal operating position. When it is pushed in to the cut-everything-off position, the knob is not readily seen and it looks like a vent knob if it is noticed.

Carry spare fuses.
