I suppose that a newer engine might have some mods on it that your ones does not, that might explain the pipe thingy's, as Cynic says carb and electrics should be the same, I rewired my XJ a few years ago and could only find a US loom, I had to cut off loads of 2 way connectors and solder on 3 ways to the lights and such but the engine connectors were the same, it appears that American riders are incapable of turning their own lights on as theirs come on when you turn the ign key, perhaps they can't reach the key past their belly? (WAIT FOR IT-- loads of abuse now arriving from over the pond)
