Hi everyone,

I'm new to the club. Just purchased my first 2009 Lexus LS460 AWD swb. It's got the adjustable damper (sport or comfort) and a height high button.

I need help with the datasystems product. Which controller and wiring harness do I need? Is there a difference between the models of datasystems? I also read you need a speed sensor harness?

If someone can guide me to the right source or persons. That would be great.

I believe for 2007-2009, the Data System ASC680L controller and the H-087G harnesses (main & speed) are the only options available/needed. I installed both myself on my 2007 Lwb in MAY 2020 and have not had any issues. I would start with the below threads for info on set up and installation. While not 100% accurate and/or clear, the first thread will help in general, and then it's easy enough to configure custom settings once it's wired and operating properly. The second thread, I used the pics to access the suspension module and connect the main harness to it. I mounted the controller in the glovebox rather than the ashtray. This is fairly easy, however, removing the nav unit to install the speed harness takes more time and patience. But for me, it's the proper way to go than without it. Good luck!
