what transmission are you running and how did you make the trans crossmember work? Also did you install a manual rack? looks like you left the factory v6 rack in with no p/s pump.
Have you tried clearing the code with a handheld tuner or scanner??...its not going to go away without trying that and was prob set just by unpluging the airbag connector i know this happpens to me a lot at work (I work on Mercedes).
