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

I'm at work right now but I'll take a look at your thread later, thanks!

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

..and the only shielded wire on the engine harness.

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

yes

Ah! That explains it. It must be that brown part

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.

weather proof spade connectors. 6.4mm

It's all in that thread
