Can s90 seats be fitted to S60

[AnttiH31]

Have you started the engine? The side support and massage is only operational when the engine is running.

I did not. I just switched the ignition on and then tried the settings. I thought that it should work with only the ignition on since the lumbar works on the old passenger seat and the thigh support also worked on both seats.

I will try it with the car started tomorrow!
