Hi jugbelly,
Hopefully the attached Photo's will help ...
1. Front Switch location
2. Rear Switch location
3. Connection socket location for Front and rear Heated seats
4. Connection sockets / plugs at rear of Fuse box on left hand side -
The wiring loom from the heated Seat connectors
appears to run to these connectors,
but I have not delved any further to confirm this, or which fuse supplies power to them.
It does seem a little strange that the Owners Manual does not identify which fuse covers the Heated Seats
