And now let's talk about the mysterious X6031 connector mentioned in the YouTube video.
You can find it in the electric box on the passenger side under:
The pin out looks like this:
I'm also attaching the wiring diagram and I apologize if the writing is so small, but I can't figure out how to PDF it in a readable fashion. Just bump up the zoom to 400%.
In our cars pin 3 and pin 9 are not used. If look at the diagram too you'll notice that A7000a is the transmission control and S227a is the gear selector switch.
It is unclear for the wiring diagram whether pin 3 and 9 of the X6031 have no wire only one side or both.
I hope this helps you guys and I'm really looking forward to see if anyone can go somewhere with this.
