which is for the twin spark R1150RT

Now we all know the company line that there have "never been any issues" but even so, it seems BMW decided to fuse the headlights on the twin spark 1150 according to Doug Raymond's schematic for that model.
Knowing that there was almost no documentation on the dual-spark schematic, I worked with Doug Raymond over the winter to get him the documentation to update both the single-spark, and then to create a dual-spark schematic. Doug put a lot of time and energy into the updates.
