According to my owner's manual on a 95, it says to look on the ECM for the five digit code. For that year, the bloody thing is buried, really buried up and behind the glovebox. I've recently had to pull a few. Access is easiest by opening and dropping it all the way upside down by pushing in on the sides. I don't know about your year, but I'm a little less stingy with the info than Rod.
Just kidding.
