Help finding o2 sensor connector from harness

So the previous owner decided to splice the o2 sensor on the car directly to the wire coming from the harness, since then I've bought a replacement sensor with the factory connector on it. I suppose I could always just cut and splice this one but I'd rather not, any idea of where or how I could find the connector that would be on the engine harness?

It's just a spade connector, 3.4 mm if I'm not mistaken

I broke mine off during my rebuild. This may be of help to you

on an S4 turbo the o2 is on the same little branch that does the BAC valve and the ACV solenoids.

^ Can you elaborate on that? I've not found a shield on mine. Is the shield a couple inches behind the connector?

Ya I know where the o2 sensor is, I'm trying to find a connector for it since previous owner just spliced the o2 right into the harness instead of using the proper connectors.
