Ok. Here goes!
It was not very hard to make it fit in a BIS.
First you have to take it apart. so you have the plate that the point are attached to. take of the point the black wire.
Then take the round thing in the kit, you have to modify this a little, it is a edge on one side, you have to remove this so it can slide futher down.
Now you have to insert the plate in the distuber again. mount the ring in, and now you have to place the module and you have to marked where it going to be attached.
Now you have to drill the holes you marked up. You have to drill through both plates, and use a M3 tap to make thread, you can make thread through both plates. (The screws go through just the top plate when you use the screws that came with the module. use only the small washer.)
Now you can attached the module with the screws.
And mount everything togheter.
