That is correct, these fit OE 96/97 headlights without any major modifications, if any at all. I am not aware if they will fit 94/95s, but I think they will physically fit. However the refracting lenses would likely interfere with the beam pattern from the projectors.
The details on installation and fitment are mostly on pages 2 and 3. Be sure to note that the pinout of the wiring harness has to be modified in order to take advantage of the high beams, as detailed in this post.
