Where is this central convenience unit you speak of Del?
I recall from working with the compressor relay that there were at least two free/empty relay 'seats' there, however that's at the front passenger footwell hence probably not the most useful location for this. However I agree,it would be a very neat job if done that way.
In fact I think I have a spare relay which I bought from the stealers As a backup for when I was dealing with the compressor!
New project scope agreed!
