It's hidden behind the left plastic cover underneath the tank. IIRC it's a female plug, plugged on a male "dummy" plug, that you could actually re-use provided you have the metal connectors that fit in. Otherwise you can find them or the whole plug on ebay, it's the same as on the MT07.
Let me know if you have trouble, I'll try to be more specific at home where I could check my ebay history and past pictures. I used mine to plug my heated grips (I had to change the fuse).
