    The only differences up until about '86 on the engine side of the fuse panel is going to be the wiper motor/washer pump, and how many headlights you have (2 or 4) other than that, an '85 will work fairly well if you can't find an '81. MJ has posted the url for them on here numerous times, try a search by username (his) and wiring or diagram.
