my son replaced the battery in my 2000 STS and did not reinstall the back seat. When I went to install seat I saw blue connector w/wires laying there not connected to any thing. Should it be or is this some kind of a checkpoint. Thanks for any response.

blue connector under back seat not connected to anything.

it could be the vapor duct.. battery vapor vents are connected to the battery to vent the hydrogen & gases that may build up in the case.

Jason, thanks for your response but I don't think it's any kind of duct. It's a little blue plastic connector about 1/2 inch cube, w/some wires going to it and it's not connected to anything via female end .

If you have heated rear seats like i do its the power wire for them there should be a matching plug on the seat.
