What year? I believe the pins were different between S4 and S5. For an S5, the stock O2 sensor goes into pin 2C. It's the middle plug on the ECU, and the top pin second from right. Black wire.

Download the non-turbo fuel and emissions section of the factory workshop manual at www.fc3s.org

It's under How-To's.
