Spoke to Allon White they tell me the relay is the one on the right of the fuse/relay box. (Looking at bulkhead from engine bay). I have already swapped that one out so they are going to plug in the 'Magic Box' on Thursday...might be ECU or sender unit on the cylinder block (behind alternator).
Looks like they may as well do the timing belt as well now - and I was looking forward to that (bought the bits and tools already!)
