Can s90 seats be fitted to S60

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?
