Apprentice,
YES, it should work. If you look under your hood on the passenger side where there is a bunch of writing, it should say OBDII Compliant. Mine does and it was produced in 8/94, purchased in 10/94 as MY 1995. When it's hooked up to scanners, it works just fine, nothing missing or anything. Provides all info, to my knowledge.
But double check under your hood just to be sure.
