Difficulties with o2 sensor

Was getting around to installing my downpipe yesterday, got down into the pit and started to mess with the o2 connectors as a first step. I disconnected them and attempted to test fit the sensor extension harness that was included with the dp from zzp.

The connections on the extension are squares, and my stock connections from the sensor and from the car side are both trapezoids, so obviously it will not work.

Did zzp give me the wrong harness or is this the only style available? I looked online in a few places and I cant find an extension with the shape I need.

On zzp, shopping for the o2 extension harness, there is one option that says
"Front 16 inch" and then there's one option that says "Rear 04+". That kind of makes me feel like I was given the wrong one? The picture on zzp looks like the one they gave me. The one they gave me is definitely 16"...
 


Also, on my 08... does the o2 just monitor the cat efficiency, or does it actually affect fueling/mileage/performance?

Just wondering if I can put the new dp on for now and screw in the o2, just not plug it in until I get this harness thing figured out... and put up with the cat inefficient code
