I am installing a anti theft starter shutoff relay in my 73 challenger. This relay breaks the ignition lead from the steering column to the starter relay. 1 wire to starter side, 1 wire to ignition switch side, 1 wire to ground, and 1 wire to negative side of an on/off switch.
I have a rear defog switch and planned to use it for the on/off switch, only problem is that I don't have a wire connection in the new harness, my thoughts were to run 1 wire from the switch to ground and 1 wire to the relay that called for a negative lead. Will this work?
This relay will activate when the ignition is turned off and will not put power back to the starter solenoid until you turn the switch back on, once the engine is started you can turn the switch back to the off position.
