Does anyone know if I will encounter problems if I put front seats out of a '93 LS400 into my '91 LS400? I know they'll fit and bolt up correctly since the look identical, but will I get an "AIR BAG" malfunction light on the instrument panel or something wierd like that? Will the wiring underneath the seat of the '93 connect properly to the wiring that is in my '91 so that the power seat controls will still work?

My '94 front seats are in bad shape, if I can find '90-'00 LS400 seats in good condition, it would fit without much modifications ? I need someone confirm this before searching for replacement front seats. TIA
I swapped a set of '94 LS seats into my '92. As stated above, the electrical connectors are different and there are a couple of extra wires in the seat side of the connector that aren't in my '92. Wire color codes are a little different too. I traced everything down using my best logic and everything works except for the seat heaters. Going through the seat heater diagnosis, they should be working, but don't. The '93 and '94 have a full featured passenger seat, nicer than the '90 - '92.

I've seen a first gen Lexus with different seats, not sure which ones they were, the windows on the car were tinted so I couldnt get a good look. I left a guy a note to call me, but he never did 
They looked like either ES seats or 2LS seats.

Yes, both fronts and the rear. My driver's seat was getting bad and I found the correct color out of a JY in Fl. Ran about $700 back in '03.
I can get you a set of seats from a 1993, 1992, and 1990. However, I can't remember the color leather of each at this time.
Let me know if you'd be interested. We'd have to work something out on shipping.
Also, 89-92 have a different harness compared to the 93-94, and I have no idea what the harness is like for the 95+.
Another thing, some of the 89-92 seats do not have as many power adjusting options such as the 93-94 seats (headrest, lumbar)...or maybe the loaded models only have them...?
Let me know if I can help ya bud.
