Hey everyone,

Need some help here on how to wire a relay to do the following:

When the relay sees ignition power, I'd like it to shut off constant power to another relay.
When ignition power shuts off, I'd like it to send +12V to the other relay.

Is this possible? How would I wire this up?

Thanks!!
