Can s90 seats be fitted to S60

This looks like the back of the seat and according to the pipes there you should have side support and massage. 
For the side support 
You should put the settings  243 POWER ADJUSTABLE SIDE SUPPORT to 81 (both cushion, backrest driver and passenger). Even though the seat may not have on the cushion, that's the only way make it work. At least on my seats.  For this, you will need to wire pin 15. Take a look at the seat's harness connector and check if you have the wire. 

For the 240 LUMBAR SUPPORT >  4 way lumbar support.

This is a picture I found online of a seat with massage that has much more air lines. Since the massage feature has 10 massaging spots, shouldn’t there be a lot more hoses going inside the backrest like in this picture?    


I have the settings you mentioned turned on but it doesn’t seem to be working.
I’ll check the seats connector.

Right now I only care about the lumbar support since it’s currently at the most out position which is really uncomfortable for my back.

But the lumbar support shouldn’t be connected to the side support feature and should work by itself right?
