I looked through the relay diagrams but wasn't able to find a relay diagram that would do the following:

I need to have a relay create a ground output when 12v power is removed from the relay. Is this possible? Can anyone share how to do this?

Thanks

Power to 86. Ground to 85 and 30. 87A will have ground on it when power is removed from 86
