Ok, at a glance comparing dads truck to mine...He has the same plug setup coming to the seat, as I do...BUT he has different colored wires in that harness going to the powered parts to move the seats...So I dunno whats different their...My truck has a build date of like 10-02, and his is like 2-03...so guessin its the build dates...they both title as 03's....Im gonna look deeper into the wiring parts, but looks like all I need is the elements, and the switches possibly!
