Help wrights with several quests, then he'll want you to gain access to SAD because his guys failed (you'll see why when you get in there :d).
In other words, go to the reno, talk with wright's son (long hair dude in upper building), he will send you to his father, who will want you to investigate death of his son. You will need intelligence of 7 or Sulik in party to finish it (Mentats usually do the job).
