If you look at pictures 1 and 2, I attached the wiring schematic for the power seat. I cut it in half to make it more readable for you. I did overlap it so you can easily follow it. Pictures 3 and 4 are the only ones I can locate for the seat belt warning system.
Let me know if this helps or of you have other questions.
