Relocated my controller from the glovebox to a more permanent location. Had to modify the back of the cup to run the harness through but it came out clean.
Pretty pissed at myself though, just as I got it all back together I realized I forgot to tuck the mini-usb cable that you can see there

Another update. Recently I installed a ASR681 wireless suspension controller that was sold to a guy that had a 2014 LS460. He never installed it because he didn't realize he did not have factory air suspension. He sold it to a guy with a 2009 460L with AWD. I installed the controller and harness with no issues. So it seems to me that the H087G, H and I harnesses are all the same and work for 2007 to at least 2014 model . The harnesses don't have the model number on them however but I find it interesting..hmm
Just an update. I can confirm that the Data Systems main wire harness (H-087G) from the 2007 to 2009 LS model works on the 2010 to 2012 LS model which calls for the (H-087H) harness. The other smaller harness that connects to back of Nav Screen for the speedometer feature that most of us don't use anyway and is not required may or may not work..but the main harness that allows the controller to work is not an issue. So if you are buying or selling a data controller. ..if you have a 07 to 12..the wire harness shouldn't matter whether you have the wired to wireless controller.
I got the ASC installed on my LS600hL and set my ride height 3 on the front and 2 in Memory M2, Above a certain speed, the "high height" is lit up on the dash, does that mean the ASC is raising my car? or is it lowering my car like the stock ECU?

Drop your glovebox and look for the ECM with identical connectors. Remove the connectors, install the DS jumper harness, plug in the connectors, run the wiring for the controller wherever you like. It's really very straightforward.

I would just love to make sure I dont do any mistakes breaking something etc. Noone have a guide with photos ?
The wooden trim comes off, pull it off from the bottom, then you'll see three screws. The cover on the bottom comes off by pushing the tabs, then the knee bag comes off, two bolts on the left, one on the right.
then there's two more screws that good the glove box to the dash.
be careful and do not over tighten when installing in reverse reverse order or you will strip the hole.
There's YouTube video on how to remove the navigation.
