Can s90 seats be fitted to S60

[Pliind]

Is the seat track sensor something that needs its own connector or does it talk to seat module?  >> No, Seat tracker sensor goes directly to SUPPLEMENTARY RESTRAINT SYSTEM SRS via PINs 13 and 14 of the seat's connector on the floor.  

Also when connecting to front door CAN, what wouls be the best method? Cutting and solderingnor do you have a better solution? Also i am missing these connectors in my harness so just i just connect to chairs wiring?   >>>  I looked for the repair terminal part number for the seat's black housing online but could not find it.  I could visit the dealer and ask for the part number but visiting the dealer here is just wasting hours even for asking a part number.  I Would prefer the original repair terminal but I added up using the dark blue in this set for the power wire of the massage seats on PIN 15.   The set include the wire tabs too or you can use soldering too. It's up to you.  

I have two rear door harnesses that can be donor pins if any connector has the same size.  >> You don't need to go to the door module from the seat, you can tab the wires inside the car. Just make sure the wires you are using are twisted and at the end of it where you tab, put electrical type around to avoid releasing the twist.  If you are referring to pins for seat connector, don't bother I checked. None of them fits. It's a pain in the bud connector.  

Thank you so much for your answers, i think I'm ready to do some snipping and some soldering. So when i connect CAN and activate seat tracker my seats should come alive! Exciting! right now my drivers seat is in maximum rear and maximum back position, feel like a child driving  (only driven short short way from appartment to my parkingspot.)
