Using this diagram - you should have continuity between 30 and 87a (normally closed) when the relay is not energized. When it is energized you will have continuity between 30 and 87.
When the unit arms ground is sent to the relay coil pin 85. At this point the coil is not energized, but If you put the key in and try to crank, ignition voltage would be applied to the other side of the relay energizing the coil and opening the starter circuit.
Be sure to use Ignition (+)12v to the relay coil that way you wont have a constant 12 volts going to the relay potentially draining the battery.
