I'm installing an O2 manipulator. Have found the O2 sensor, no problem, but when tracing the wiring back to the factory connector I loose it in a wiring harness. I think I have found the connector directly under the gas tank, but would like to confirm. On my last Duc the connector was under the seat.

The O2 Sensor side of the connector will have 2 white, 1 black & 1 Grey colored wires. I don't have the wiring diagram for the 2007, but the 2006 ST3 diagram lists the ECU side of the connector as Light Blue, Green/Blue, Red/Black & Black/Blue.

On my 2007 it was on the left side up under the mid fairing. I could just reach it by taking off the lower fairing.

Found it!

Located under the front fairing, thanks all for the input.
