Thanks for the suggestions and help guys but ive now found out what the wire is!
After looking over the circuit diagrams again last night I noticed the solitary black wire that I must have missed when checking the diagram earlier  (amazing what a couple of glasseds of wine can do!)
It appears that the wire is a secondary earth that goes directly to the battery and also has the front indicator earths spliced into it about halfway along the loom so just need to make up a connection to the battery and fix the snapped wire from the neutral switch that I also found last night and hopefully the XT thats been sitting in bits in my garage for almost a year might actually be running this weekend
