We had the rear seat in our wagon when I was growing up. I managed to find the rear facing seat for the 740 wagon with the intention of doing the same for my kids. The only problem is there was no approved way to fit a car/booster seat to it, and by the time the kids were out of the booster seat they're over the weight limit for the seat itself. So it was a complete waste of time and money.
It doesn't need me fiddling with connectors to make it stop. It's perfectly capable of doing that all by itself.
