Well spotted Wildrice I never even saw that female socket lying there before!!
on the T595Net site they have decided that the spare socket under the tank of the S3 is because it uses a Speed Four wiring Loom.
By the same logic this spare socket on ours could hint at the existence of a Triumph Speed Quinn!!! :roll: . Now that would HOWLLLLLLLLLLL even more than the speed-carrot!
The socket on mine is so dirty I don't think it has been used, in addition I can't find a male socket empty for it to fit to. After 3½ thousand Miles mine runs really sweetly all the way to 13k with no flatspots. So I reckon the socket is from some other option for that wiring loom and it is OK.
Good luck & keep your eyes peeled it is very helpful!!
