Sorry to bump up such an old thread but I'm wondering if anyone has the factory diagram for the connection of the passenger side heated seat. I went through this discussion (and some of the related wiki items) but didn't find that info. I had to swap my original non-heated seat out because of a broken occupancy sensor. The replacement is heated and I'd like to hack the wiring to get it working but I've had no luck going through various PDFs found here including PG (power supply, ground, circuits), SE (seats), HAC (heater and AC control), HA (heater and AC).
If anyone has a lead on where I can find the breakout of that seat heater connection I would be very grateful.
