I am working on a 2008 650 and have disassembled the airbox to remove it from the bike. In the process I broke one of the nipples that connects a hose to the bottom of the airbox. This nipple has an electrical connector on it so I assume that it is a sensor of some kind. It is on the RH side of the airbox when sitting on the bike and has a hose connected to it that joins into a hose below it with a T connector. The sensor is held onto the airbox with two phillips screws. I have looked at numerous diagram of the airbox but cannot find anything that looks like this sensor. Any ideas what it might be? Thanks very much.
