Can s90 seats be fitted to S60

[IMAY2023]

yep, it should as is. You'll need to wire pin15 for powering massage seats and side support (5amp) same fuse is shared by both L&R seats.

Thank you so much for confirming!

Hello!
I changed the seats in my 2018 V90 (LHD) from semi-electric (height and lumbar adjustment) to fully electric seats with massage and cooling. I modified the electrical installation as I found instructions on this forum. The problem is as follows: both seats are passenger seats, one seat comes from an S90 RHD, and the second from an S90 LHD. When I give the command from the driver's seat, "passenger seat" appears on the central display, and the massage and lumbar adjustment do not work on either seat. The memory function only works on the passenger side, not on the driver's side. How do I tell the car that I have a driver's seat on the left and a passenger seat on the right?
In ORBIT, I activated the following:

• 179 FRONT SEAT VENTILATION - 02 Ventilated Seat
  
• 184 POWER SEATS - 04 Driver and Passenger Memory Seats
  
• 239 MASSAGE FRONT SEAT - 02 Massage, front seat
  
• 241 CUSHION EXTENSION - 03 With Cushion Extension, Driver & Passenger
  
• 243 FRONT SEAT POWER SIDE SUPPORT - 83 Power adjust side support backrest, driver & passenger
  
• 244 REMOTE CONTROL OF PASS SEAT.. - 02 Remote control of passengers seat functions
  
• 350 MEMORY BUTTONS, IF POWER SEAT - 02 Two (2) memory positions
  

Thank you in advance.

The problem is the software of the seat controllers. Since both seats are actually passenger seats, bothe seat controllers are programmed as PSMP. 
In addition, passenger side seats have occupant sensor while driver seats don't have it. 
First, put your original driver seat back and try to make the passenger seat fully functional including controllering the passenger seat.  
Then, pull out your original driver seat controller put it on the new "RHD passenger" seat.  It may not work with all the features because your controller might be missing some PINs.
If that does not work, most likely you will need to flash the controller. Not sure if it's possible though. Another options is, find a used PSMD from an LHD car that has all the functions.

The original seat does not have a PSM controller. Can Orbit rewrite the PSM controller?

[IMAY2023]

Orbit can flash some of the ECUs but you'll need the correct SBL (bootloader) and the software files for it. Send an email to support, they might have. 
It's strange that your original seats don't have the controller since you mention they are semi electric.

it's simple! there is a black PIN A21 wire on the unit, cut it on the driver's seat! it is only needed to identify the passenger seat! and the car will understand where the driver's is

[IMAY2023]

NO! A21 on the PSMP is the ground! and not all the variants have that connected. 
My original 2019 S60 Momentum LHD  full electric heated passenger seat does not even have the A21 PIN on the controller.

Thanks! I'll try it in the next few days and get back with details.
