I checked my last Full year NJ W-2 from 2001, and the full amount of the 401k contribution was deducted from the NJ state wages (box 16).
It would have matched box 1 exactly...except there was ~$490 added back to NJ wages for some other Federal Cafe 125 deduction that NJ didn't allow...don't recall what that was for now 20 years later.
