I double checked before fitting, and when re-fitting. The old OC81 had a spot of coloured paint by the collector wire which is insulated with red pvc in the shots in post 20. The new OC81's had a rubber jacket with a grey line by the collector. Assured this was correct, that is how they were fitted, same location as the red insulated wire, though the layout of wires as the exude from the base of the units is an a triangle that is opposite to the triangle of holes in the board. The original OC81's wires were located in line, so the pattern appears irrelevant.
