I passed my Autcom cabling to Cannon in Chelmsford to be fitted PDI. Despite providing written instruction with pictures of an instalation such as the one you are working toward, they still delivered the bike without the manual bracket! By way of an excuse for it's absence they said that they provided the manual in a folder and so did not install the bracket!
When I quoted this to BMW UK in a letter of complaint (about far more serious issues than the bracket, but just to give a general picture of my disatisfaction) Cannon suggested I must have misunderstood. I may well have, our disagreement goes on!
Suffice to say they handed one over when I demanded it at delivery, but I had to fix it myself!!!
Go ask for yours....?
PS. I found the red/black GPS/Phone splitter fits nicely under the tanks side panel.
