I had posted this question back a few months ago with no replies. I had searched the web found nothing. So I finally dug in and figured it out without triggering the airbags. See my post “Hard back seats airbag delete”.
Under the seat there is a Yellow connector. If you take it apart you’ll see two small grey connectors and a large back one. The grey connectors are for airbag control. The black one contains heat and seat power connections. There is a “dogleg” to the connector and the spades (pin) are offset. There are red wires to the upper spades and brown (ground) to the lower ones. The red spade in the dogleg is for seat heat. The other one (in the center) is for seat power.
