SO, I am thinking, if there is a way to have a relay that is activated with POWER OFF, I would be set. Do they make such a thing? Power goes off and switch gets activated?

You would have to route power through the relay so that it energizes the coil... and then you want to find the normally open, contact and run power to it and you connection on the other side...
That way when power is off, the connection is closed and when power is on the connection is open.
You have to understad how relays work, when the power is to the coil, meaning you have 12v to pin one and ground at pin 12 thats typical setup for a relay.
Then you have the other pins, and you have to figure out which ones are normally open and normally closed... TYPICALLY the ones normally closed, are the ones on the ground side of the coil...
Take a picture of the schematic of the relay if you need more help and I can tell you what you need to connect where...
Nomally open and normally closed are to be understood that the coil is not energized.
