Well, it was awhile ago. So let me see if I can stumble through this.
I wired up the drivers seat like shown in here. Then I spliced the new pass switch grey, black, brown wires into the drivers side switch. Then I ran the pink and blue wires from the pass side switch through the console and under the carpet to the pass side seat connector. The blue wire goes to Pin D-Driver Heated Seat Relay Control. And the pink wire goes to Pin B-Driver Heated Seat Cushion Temperature Sensor Low Reference as well as Pin E-Heated Seat Cushion Temperature Sensor Signal.
Then just cut and glue the two sides together for the switch bezel and you are done. I hope I got all that wiring crap right. Someone let me know if I didn't.
So here are the completely unprofessional pictures of a dirty daily driven car:
