Confused with these knock sensors

Hey all. So I'm putting my new engine and trans in and I bought every sensor brand new from ford. However, the knock sensors they sent had two separate connectors while the harness has a single 4 pin connector. So, I ordered the right one from LMR. I got it today and the connector is correct but the brand is Standard part number KS189. I'd rather use oem but I have no idea where to get the right one and I'm not sure if I order it from somewhere else if it will be the right one. Are Standard sensors subpar or are they as good as oem?

I had good luck with Standard brand. Never used a knock sensor, but TFI modules, distributor pickups, cap and rotors were all good. And tfi modules I definitely had fail in a few minutes after install, none of the Standard brand modules ever failed that quick.

The correct Ford part number is 1L2Z-12A699-AA... (two sensors one plug) They are available from Tasca Ford parts for about $66.00
