Schematic

Found it in the schematics.
The three wires from the ecu "T" into the three wires from the ignitor to the coils.
What I thought was an output from the ecu to the coils is an input ( motor speed).
The ecu only controls the injectors and the ignitor manages the coils as per the previous models.
If you already know this just ignore it, but my past self will find it informative.
Cheers
