ACC cable, where does it go?

ACC cable, where does it go?

Ok, so have just got the unit, and now im doing to then prep work so I know what hell im doing when i get this fitted (when the rain stops)

Anyway so I have worked out where all the cables go bar the yellow one, as I am not sure where that acc cable is supposed to be connected to.  I have watched the installation vid and that seems to indicate that it can be connected alongside a fuse but there is no indication which fuse or even if the fuse is part of the main bike fuse box.

Now I can make the assumption that it can be connected with the power source fuse, but as assumptions are the mother of all cock ups I want to make sure before I do anything.

Just means I can get everything else connected with power being the last thing I do.
If it makes any difference it is being fitted to a VStrom DL 650
