Seat swap, type 44

Hi Cody,
Maybe it's me, but this sure seems complicated.  I had naively thought I'd
just plug the new seat in and go on my merry way :-(

I pulled the entire harness out of an old seat.  Swapping it over to the new
seat seems like a fiddly excercise the way everything is jammed up
underneath.   I think your  analogy with Humpty (all the kings men, etc ...
) is right on.  Plus I think it would be a useful harness for other future
seat swapping.  So I'm persevering to try and match up wires to create an
adapter harness by splicing the seat side wiring/plug from an old seat to
the chassis side wiring/plug from a newer seat.  This would alow me to plug
a new style seat into the older car without cutting any of the wiring.  This
too is turning out to be more difficult than I bargained for.  My wiring
diagram reading skills are not the best and this seem like it's well beyond
the beginner level.  Anyway, that's where I'm at ...   poring over diagrams,
sketching everything out, and checking it thrice I cut anything.  Still not
sure this is going to work.  I may end up trying your approach.

Jesper Mopreau makes it sound so easy in his KnowledgeBase write-up.  Maybe
once I get it all figured out I'll think it's simple too, but I'd be

Thanks for sharing your BTDT.
