You need to get a tank ring (#6 for triumph) too. Have fun attaching it the bolts are all messed up sizes haha.
You also need to drill into the bag to put the bolts through it to fix to the topring for the bag, quite easy it comes with a template and the necessary bolts. For me though the bolts for the top ring into the bag two were too short, conveniently i had 2 spare longer suitable screws left over from another project

.
As i said ill take a few shots of it fitted to the bike when i get home. I got an electric set but ive also got a non electric set - though it isnt fitted.
One thing about the electric set, it really needs spraypainting as it sticks out badly :P.
