Is it the kind of carrier that has two slots in the backs of the harnesses for the connector thingamajig?
Yeah, like that makes ANY sense!
What I mean is...our bucket has a metal connector piece (the splitter plate) in the back, behind it where the harness slack hangs....the plate holds the harnesses together. The harnesses have two "slots" or "pockets".... one is used for the littlest babies to get the harness as tight as possible, then when baby grows you put the clip in the second slot so there's more harness to work with. Maybe (if your seat is like this) yours is in the bigger baby slot.
Does any of this make sense?
Our seat is the old SafeSeat 1, if that helps any.
