Hi,
I just completed installing the Oxford grips on my 2011 B400. My controller is very different from the one shown in the above responses. Hopefully the link below shows the controller used in my version of the Oxford grips:

If so, the mounting is pretty tricky, as the unit sticks to a metal plate that mounts to the 2 screws that hold either brake unit onto the handlebars. Not an issue with most bikes but the Burgman tupperware gets totally in the way. If you are in this situation let me know and I'll take some pictures to show you where i made 'some cuts'. Hopefully you are one with your Dremel tool...
Otherwise the install went well. Refer to the videos online (micsbergsma) to know how to grind off the old white plastic under the stock grips (again, using a Dremel tool).
One conclusion I reached was that I really wanted a switched fuse box in my scoot for farkle such as these grips. The chance of leaving them on is just too great. So I purchased the Eastern Beaver PC8 and following the wiring diagrams on LeDudes site, my next project is to rewire the whole shottin' match.
BTW the heated grips are really nice. Next I want to add some heated clothings (one more reason for the switched fuse box). I learned researching this forum that a battery monitor gauge is a good idea so all this farkle doesn't beat your charging system in keeping the battery happy. So I ordered the Kuryakin unit which everyone likes.
So there you have it. One good farkle begs another good farkle. It never stops (I hope).
Good luck.
