Hi, hard to understand, but will try to help.
I would use the same wiring like original BOSCH 0 221 503 457 says.

For example, I got BREMI 88113 alternative coil and it lists different wiring layout, but when i tried to follow it, i got violent spark timing while engine cranking (engine won't fire up).
So connected like old BOSCH was, and it fires perfectly.
This is how i connect, look at the picture.
