so you have everything working now?

You are right. Finally the seller has sent the modules to me and now the seats are complete
I live in Europe, my lexus was imported from US and there appears a new problem... One plug under my passenger seat does not match the plug in the european Lux p​​​​​​assenger seat. There are 3 plugs in the car- yellow, white and grey. The grey one does not match the plug in the new seat. On the passenger side it has 6 wires while the plug in the lux seat has only two wires, two pins.
Anybody know what the grey plug is for and why is the difference in american and european GS?

Not sure what it's for but the color of the wires on your Gray Plug might correspond with two wires on your new seats gray plug. All you might have to do is tap the wires together.

Before doing that I would just plug everything else in and find out what doesn't work.

I would start with the latter: otherwise you can run into an issue of shorting something out.

Super rare and hard to find. All the Parts for auto heated/cooled front seats and auto heated rear seats for the 2013 450h. Just add it to the long list of parts I have and pending mods

I just have non auto heated and cooled seats in front. In rear non auto heated.

Took me this long to get the correct AC amplifier from 2014+ 450h lux, before I had the 2013 lux ac amplifier.

baconRx

gotcha I never realized the rear had auto heated option

Can you add Auto Heated & Cooled seats with just that switch set? Does that enable changing how the auto works in the infotainment unit?

No you need the correct AC amplifier from a 2014+ GS.

Do the 10 way adjustable (F-Sport) and/or the 18 way adjustable (luxury) adjustable side bolsters adjust wider than base/premium rock hard seats? My 2GS seats are wider, softer and much more comfortable than my 4GS base/premium seats.

Thanks...

My 3GS seats are much more comfortable and substantial than my 4GS seats. If I was buying furniture, I would pay at least 2x the amount for the 3GS comfort.

The 4GS seats are probably the least comfortable seats Lexus have made. They're also probably up there with being the most supportive (Fsport).

I am not sure of the answer to your question, but to clarify, the F Sport driver's seat is 16 way.

This surprises me. I'd rate them as some of the best that Lexus has ever made. I absolutely love them.

I agree. The only thing I miss is the seat bottom extension from my ‘14 F-Sport. Other than that I don’t think my Premium seats are any less comfortable on my new ‘18 Premium. I drove over three hours from Santa Barbara to Palm Springs this weekend and I was perfectly comfortable. No different than my ‘14.

As far as the leather goes, yeah, I guess I wish these seats were leather. But then again maybe in 2-3 years these will hold up better than leather which tends to crease and crack at the bolster.
