Note:
Photos show MY2007 S80 installation. Installations in other car models are similar and the same principles apply.
1. OWS spare part kit and seat frame.
2. Route the wire harness with OWS ECU and
pressure sensor through the 3rd and 4th
spring wires.
3. Lay the bladder package on the springs with
the hose below them.
4. Attach the push pin and attach the pressure sensor in the bracket. The hose port shall face the right outboard side of the seat (see photo above). Make sure that the port is not pushed up into the seat. The hose shall be looped in a smooth curve to the front of the seat in a clockwise direction (see photo above) and the pressure sensor shall be mounted with its connector facing the front of the seat.
5. Make sure that the hose is correctly installed (routed in a smooth curve below the spring wires) and the pressure sensor is attached in the bracket without external interference.
Note:
For vehicles with seat heating, install a new heating pad along with the OWS spare part kit. This is required in order to maintain a proper mechanical interface in the seat.
