Key-In-Ignition Warning

The Warning Alarm applies voltage at all times to the Ignition Key Alarm Switch. When the Ignition Key is placed into the Ignition Lock Cylinder, the Ignition Key Alarm Switch is closed. When the LH front door is open, the LH Front Door jamb Switch closes the circuit to ground. The Warning Alarm senses a voltage drop at the Ignition Key Signal and will sound the Ignition Key Warning.
