Yet more really useful info Rog.
Just one question, does this discovery alter the diagrams that you shared with us illustrating the mods you had done, back in May. I believe that in those, the fog relay coil was supplied from the sidelight wire (R/O 76).
Think Richard queried this at the time as to whether it should be driven from the headlights though consensus was that Morgan had adopted both methods over the years.
Thanks Doug, good point. I think its dependent on you your preference. I’m a bit of a dinosaur so quite happy with my rear fog coming on with the side lights, there are reasons why somebody might do this. However, others may be more comfortable with it working only with the headlights, more like modern cars. Either way I believe both approaches are perfectly road legal.
Re the diagram. I’ve updated it to show an either or option.
Configuring it is quite easy. Wirh reference to the diagram, you either connect the Scotch Lock connector to the red/orange wire or blue wire running in to this connector.

Roger, thanks for continuing this thread. Incredibly useful information as replacement boards are very difficult to source let alone the ridiculous cost.
I couldn’t just leave it hanging Bob
