Yes thanks I had seen that but as I had more wires to find homes for I didn't feel confident in using it. If there had been just the one wire coming in then I would have given that a go.
You are right. What is described as a simple rewiring job seems now much more complicated. Ideally I would have bought a replacement ST7100 but they seem to be unobtainable. If you know of a source that would be very helpful.
Thanks

The wiring behind the ST7100 looks much more complicated with three wires going into the backplate but I am not sure where these wires all come from and therefore which ones are necessary for installing the ST9400C.
