and today I am completely lost while trying to figure out how the new AutoSparks wiring loom, the wiring diagramm in the owners handbook and the previous wiring should map. BS-AU7 headache galore.  If anybody has a correct wiring plan for the Morgan 4/4 with Ford CVH engine - please let me know.

This is the one I referred to when I had a CVH engined 4/4. Sadly, I cannot remember where I got it from. Please double check a few things before you rely on it. ![[Linked Image]](https://tm-img.com/images/2020/12/31/A8196411-3015-4576-9A06-6839C9E26EF5.jpg)

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.

Athough on several wiring diagrams, my '72 certainly didn't have a park switch. It may have been a regional variation.
If you have a non ballast coil you won't need the ballast resistor and associated 'bypass' wire for starting.
Might be worth looking at a much later date wiring diagram and doing a comparison?

That was a very good suggestion. Didn't think about it yesterday. The next plan on GoMog is the 1988-1989 plan for all Morgan cars. This looks much closer to the one installed on my car. https://www.gomog.com/allmorgan/wiring88&89.jpgBack to work bench... 😀👍
