Seat has to come back out to fix a couple of loose thread pieces and to fix the lazy patch panels somebody has done, so no worries there, and I'm not sure what you mean by sticks?
I had to pull the whole dash back out, remove the ducting, install the harness the right way, and then put the ducts back on, and reinstall the dash. Time consuming, but it was the right way to do it and made for an easy re-install.
Sticks = shift levers. Stick shift?
