Joe - This is what I so love about the 928 OC, individuals like you who are willing to share their knowledge. I too am bringing back to life a 1981 and have not yet found a wiring diagram - can you share yours with me please? Email is norristimothye@gmail.com. I started with cleaning the grounding points, but quickly learned that the document I was referencing was for a newer 928 and I did not have all the ground points present in that model year.
Again. many thanks1
