Are any 2 Morgans ever the same smile

Thanks Roger. I guess the clue is in the dash layout/switches which if the same will have same dash loom at least.

Assuming your dash is the same as Rog's Bob, you will have the PCB controlling rear fog operation. Note for some reason MMC chose to have the rear fog triggered by sidelight operation only. Later models including GDI Plus 4 and 3.7 Roadster used a far more robust essentially sealed BCU to control rear fog light which requires that headlights (dipped or main) be on for rear fog to work. This ties in with other manufacturers as best practice.

As mentioned elsewhere the only MOT requirement is that rear fog works when selected and has warning light.
