In the process of changing the starter - have the starter in and ready to put it all back together. But I can't remember where a particular connector goes and don't remember disconnecting this one. Can anyone tell me what the connector with the red arrow connects to? It originates from the wire box where the green arrow is. The wire box is the one connected to the bottom of the intake manifold on a 07 e90 335i.

Thanks,
Scott
