after reading though various threads on here i started the install today, got the glove box out looking for the factory air suspension controll unit and it was no where to be seen.

I checked the Japanese instructions and it does show instructions for how to acces the suspension control unit but its on the drivers side for me(right side of cabin) down where the obd2 port is. You need to remove the panel under the steering wheel

-Remove this small piece of wood trim

- Remove the 8mm screw under this
- remove the plastic panel under the the parking brake button
- Remove the screw behind it
- Pull the panel forward from the bottom snf it should come off easy enough
- Disconnect the 4-5 connectors from the back of the panel and set to one side


Here you can see the unit with 3 black plugs going into it( not like the US with 3 black and 1 white from what ive read on here)


Harness connected into factory module unit:


Factory wiring connected into other end of harness:


Apart from that everything else is the same as US models

- I removed the headunit and routed the wiring loom under the steering column and in behind the headunit.

- I remvoed the nav unit to plug the main connector into the back of the nav unit. Its held in by 2 short 8mm bolts at the bottom of the unit , they are hard to see until you get down eye level and look in and see them recessed into the dash console






Now i just need to figure out the settings of the ASC680L and find some good presets. When i turned mine on i didnt get asked for car model or anything but it seems to be working as intended.

 

Perfect write up thank you!
