It's the older module that's in the fusebox. N65 was replaced by N65/1, which was replaced by N76 and a new combination-control module N10-1 (hopefully you don't need these to repair this car).

You can see it if you take the cover off of the fusebox. Open the lid, and there are two screws inside with the fuses, and an additional screw at each corner (six screws in all). The module is right behind the fuse blocks, on the left side of the box (toward the fender).
