Phil,

Thanks for the suggestion. I have now discussed this with an auto electrician, who said this would be VERY difficult due to the lack of play on the wires.

I am trying to source a secondhand loom (new one £233 + VAT!!) as he said it would be a relatively simple job (for him) to fit.

I suppose if replacing is easy he could take the old one off, repair as you suggest and then put it back on.

Will keep the forum updated for those who will experience this fault at some stage.
