Gear sets provide bonuses for wearing 2, 3, and 4 pieces from it. 2 and 3 pieces generally provide ordinary bonuses and 4 providing a unique and very powerful bonus. Wearing the chest or backpack from any given set requires giving up the flexibility of a talent you choose yourself but those pieces have special talents that improve the set's unique 4 piece bonus.

To answer your question specifically, you don't get anything special for wearing JUST a chest piece from Hard Wired. You would have to wera the chest piece along with 3 other Hard Wired pieces.
