Yes one of the wires will be used for the ground connection. When connecting the wires from the trailer brakes it does not matter which wire you use for the brake feed or ground, the magnet works either way.
Just be sure that the wires are clear of any moving parts and that the brake feed is attached to one of the wires and that the other is attached to the trailer frame for a good ground.
