BMW K100RS Wiring

Q: Can you please help me with the correct connection of the wires on the ignition coils of my BMW K100RS? — Corrie/via email

A: The brown wire is common to both coils, as is the green/yellow wire. The blue/black wire goes to the front coil while the black/red wire goes to the rear coil. The front coil is for cylinders 1 and 4. Looking at it from the bottom, the blue/black wire is at the top, brown in the middle and green/yellow at the bottom. On the rear coil (cylinders 2 and 3) the top is black/red, the middle brown, and the bottom green/yellow. MC
