How to tell if an LS400/Celsior has adaptive air ride

[puffypuffy]

HI all!

I am looking into importing a Celsior or buying an LS400, and I really want one with the adaptive air suspension, but I don't know anything about the trim levels or USDM/JDM feature differences. Is there anything that will tell me for sure that the car has it?

I believe you can tell by the electrical wiring harness/plug on top of the front strut towers.

TBH, I wouldn't want adaptive suspension.  Especially on an old LS.  Replacement parts (if you can find them) are crazy expensive.  When the adaptive suspension begins to have issues, most just install conversion struts that eliminate the adaptive function.
