Well this has turned into a right old ball ache.I am now on my third squib as they keep sending ones with the wrong connectors on the back, I have now decided to just stump up for a brand spanker at £72,at least I will know the spring unit is correct.
The problem now is, I have to go and pick up the part 10 miles away across town and I took the old unit apart to take the stalks out,and in the process mullered(completely removed!)the old ribbon.
I am safe to put the stalks and wheel back on and drive across town with the airbag and horn unplugged, I can't see why not as they were connected to a dodgy clock spring any way.
