I did succeed, once I quit overthinking it. The seats only need a power and ground wire, in addition to the seat belt wire and whatever else you already have (it’s been too long to remember). If you can track down the wiring diagram, figure out which pin on the power seat connector is power and run a 12 v wire of your liking to it. Same for ground. That’s all they need to fully function! Sorry, I can’t find a picture of the pins after all these years. Good luck.
i got the passenger seat in today. i'm going to start a new thread to detail the swap
