I pulled the seats out of my '99 10th Anniversary Edition Eclipse the other day. After unbolting, when I pulled up on the drivers side seat, it wouldn't come. I looked closer and that's because one of the two wiring harnesses was actually plugged into the seat.

When I reinstalled the seat, I left it unplugged. Was there a reason it was plugged in? A safety thing with the air bag? Were all manual seats plugged in like this from the factory? I'm 99% sure these seats had never been taken out before...
