Thank you for the tips, it helped, problem sorted
Having taken the seat out, it is clear that there is no wire to connect to on the passenger side. It is a bit odd but that cable is useless
It turns out that the driver side was as well disconnected and that is what triggered the light. Simple job to reconnect.
When fiddling under the seat, I found a balck box say the size of a small matchbox, still wrapped in bubble plastic
That connects to a cable passing by, and hey presto, the door loud speakers that never worked went on.
Someone in Malvern started to connect bits and pieces and then went for a cup of tea and forgot to finish the job...
