That is your O2 sensor connector. The S4 and S5 had different shape O2 sensor connectors.

Here is RockAuto link to photo of S4 O2 sensor connector: https://www.rockauto.com/en/moreinfo...t=5132&jsn=423

Here is RockAuto link to photo of S5 O2 sensor connector: https://www.rockauto.com/en/moreinfo...t=5132&jsn=457
