Do you mean you have selection equations which are MNL and linear outcome
equations?  If so, you can easily execute the transformation to normality
detailed on pp274-275 in Maddala.  Note, however, that generating 
consistent standard error estimates is far trickier than getting
consistent parameter estimates.
