No, 87A is the opposite of 87. So when the relay is not energized, Power flows from 30 to 87a. When the relay is energized, 87a goes dead, and power flows to 87. Never use a wire nut on a car, they are not recommend for the vibration a car is subject to.

You want to either solder the wires together and then cover with heat-shrink tubing, or use a crimp style butt connector.

What I recommend is running a single wire between 87 on the relay and the closest fog light. Then you connect that to the wire or terminal on the fog light and then correct another wire to that same connection and run it to the second foglight. Similar to how the diagram shows.
