Wiring harness seems less complicated once I noticed they are in two sections, meeting at the combo relay.
Curious how different the ecu's are, and their matching harness's. I've noted my 635 euro has fewer sensors on the thermostat body, and there is the difference in aux air valves over the years, therefore different harness, ecu ?
Fun to see a full race engine to see how many gizzy's aren't necessary to go fast on a sunny day.
