I would not 100% dismiss these already repaired wires
Agree, I keep coming back to these wires and in particular the part which I can see has been previously repaired using the splice connectors you described. It has even occurred to me that whoever carried out this repair may have accidentally inverted the orientation of the wires.
Here's what I have at the moment...
The blue wire runs from the rounded side of alternator plug (which I believe is L) to a splice connector where it is joined to a lilac & green wire.
Tests confirm electrical continuity of this wire between the alternator plug and the ECU
The brown & red wire runs from the flat side of the alternator plug (which I believe is DFM) to a splice connector where it is joined to a blue wire.
Tests confirm electrical continuity of this wire between the alternator plug and the point where is enters the bulkhead on the engine bay side
So, in essence, on my car, the wire connected to the rounded side of the alternator plug is connected to the ECU?
Just for peace of mind, please confirm if this is correct

Good advice - already have a multi-meter!

A bit of an update here...
I previously reported that when stationery, engine running, turning the steering wheel causes the battery light to flicker. (tested many times, no particular wheel position, repeatable, but no specific pattern).
But, yesterday, I took the car for a test drive (16 miles) no driving issues...
The battery light
did not come on until I started switching things on... then, it would intermittently flicker and extinguish as the additional load is introduced.
I know some might immediately suspect the alternator but I think the 'ignition on, engine off, no battery light' scenario is a major clue?
Please bear in mind the original Bosch alternator and Bosch battery have been replaced with identical new parts - there was a charging problem prior to replacing the alternator which the new one has now resolved.
