That is somewhat encouraging news.
You are obviously an expert; it sounds like something way over the head of a DIY type with more enthusiasm than expertise ; ) , i.e. I need to have a mechanic do this I guess...
Does the harness you reference provide connections to both the seat and the door? Is it possible to modify the door panel (and have a cosmetically acceptable result) or should one buy a replacement 280 panel?
Thanks so much.
