Hi TBm, Hi Paul,
The plan on the Gomog page and the plan above (also printed in the drivers handbook) are all the same.
But there are a number of differences between the plan and what is actually in the loom (the one installed from the factory)
E.g. The ballast resistor is missing. There is a white and white-black cable to the ignition coil. This in turn has a black and green-black cable running to the distributior.
Alternator, Starter and Ignition also slightly vary from the plan above.
There is a Red-Yellow cable (Bs-Au7: fog lights) in the loom - not shown in the plan.
The park-switch (also discussed in another conversation here on this forum) is also difficult to find. My Morgan my father installed a MK dashboard with different switches. This makes it even harder to find this in the old loom.
The Autosparks loom (which does not have any documentation and is supposed Identical) has a number of smaller differences. Just takes time to figure it out.
