A few months ago I had a rat chew through all the wires of this connector - pretty close to the plug under the car. I crimped them back together, but there wasn't much to work with. This past weekend, I had the car shudder and die at idle and the same code came up.
I need to buy a connector with wires to have on hand for when I get under there to address the issue.
Can someone link me? I want to be sure I get the right one. I've found the connector housing but nothing with wires other than this (and I'm not sure this is correct as it says 'neutral version')

Maybe I answered my own question - but just want to be sure I order the correct part - and this could help people in the future.
Thanks a ton in advance!
2014 b8.5 s4 DSG if it matters.

If you're willing to do that for me that would be incredible!

parts catalog lists the harness connector to the engine speed sensor for the B8.5 3.0T as 4H0973703A, with protective cap 8K0971921A. None of those links were for that style connector housing.
Odd, for B8.0 3.0T, it was just 4H0973703. Engine speed sensor is different for B8.0 vs B8.5 though:
B8.0: 059906433C
B8.5: 059906433F > J > K
4H0...703A is a brown core, with the key slot over the "2": https://www.ebay.com/itm/265446162506
compared to the more common 4H0...703 that is black core with the key slot over terminal 1.
A different page with both (sort of), making it easier to see the key slot change for B8.5, for whatever reason they did it. https://www.aliexpress.us/item/3256806141927043.html
As to the gray locking tab, the gray locking tab versions are 4F0 973 703 terminals, not 4H0 973 703 terminals. But they are likely interchangeable (eg, 4F0 973 703 A and 4H0 973 703 A, the non-A and A of both are still not interchangeable due to the key slot difference); China sellers sure do believe so.

Thanks for all the info!
I guess the part I'd also need is that 90 degree elbow + wires behind it. Though, Shane was kind enough to send me one to eliminate all the guessing.
I crimped the last ones and assuming there isn't a new chewed wire, I just don't know how its still causing problems (though not anywhere near as bad). I know soldering is frowned upon more for automotive, but I bought and plan to use these since I will be able to twist plenty of the wire together https://amzn.to/4h4R7zJ
