I finally installed my 997 adaptive sports seats. I am continuing to have issues with the lumbar and bolsters in the driver's seat. I may be able to resolve those issues next week by installing a different air pump in the seat. I'm going to include a link to the Rennlist post that provides detailed instructions for converting the seats on my 986 Forum thread.
If you want to go directly to the instructions, start at post #73 on this thread:
