Don't do yourself down. That diagram is utter crap. It's badly drawn, wrongly labelled and thoroughly misleading. Even the coil packs - crazily removed away from the circuits they are part of, are in the wrong order.

If someone had set out to make it as confusing as possible, they couldn't have done much better.

The unknown is whether they were so clueless or whether it was deliberate obfuscation. There is the possibility that it wasn't drawn by the designer, but by someone downstream and without a scoobie.

Circuit diagrams re-worked through the eyes of a 'graphic designer' are also quite something too (this isn't one of those...).
