Had a cup of tea and a digestive, no hobnobs unfortunately.
The connector block that doesn't have the speaker wires does have a red, presumably 12v, feed, the black ground lead and three others. I have tried various combinations, there aren't that many, but still no power and not even a blown fuse to indicate I was getting close.
I suppose the three options are that the power isn't connected, the radio is faulty or I am even more inept that I thought, although I did manage to fit an Alpine Head unit in my previous Morgan.
Reassured that the block connectors should work I will get the car along to my local garage and they can see where the issue lies.
Peter I have followed your previous posts with interest on the DAB/FM splitter and have one ready to go, when everything else is working.
Thank you everyone for your advice and help.
