Well apparently Amazon agrees with Ford. Thank you - that is absolutely informative.
I never even thought to look for auto parts on Amazon! However, I will point out that the particular part you found does not fit the 2015 FPIU 3.7 Flex engine. I looked up at the top and it said that in red, I made sure to select my car and it was the wrong part. However, what they said and what Ford said about the orientation of the sensors was in agreement.
In the end - I got the part for $25 inclusive of S&H delivered to my door via eBay.
All of this "do it myself thinking" caused me to forget (and very recently remember) that there is a very reasonable Meineke Muffler shop near me that will put parts on to cars at very low rates (you need to bring your own part) and be willing to come in at a time when they usually have no people in the shop (not Monday or Friday, but during the week and you might wait a little bit). I also happened upon another shop closer to my house that would put parts on for me as well (for a bit less).
In the end, I was able to order the part online for $25 and change including S&H and then had the oil change place closer to my house do it for me for $50 total (no tax). Thus, for $75 total I got this issue eliminated.
I also learned something else...my car being a 2015 has both "pending codes" and "permanent codes". A pending code can be erased with a scan tool, a permanent code however is NOT really permanent! It stays in the ECM until such time as the ECM determines the problem has stopped occurring and then removes the permanent code on its own (my scanner can show both pending and permanent codes, and specifies which each is). Eventually the permanent codes went away and all my emissions indicators returned to green and I am good now.
I set the jack stands high enough to have room to be able to use my breaker bar to remove the part, however, the jack I had was not able to jack the car up high enough to get it onto the jack stands at the higher height. So, unless I wanted to spend $85 on a jack instead of $50 at a shop, I gave up and let a shop do it. I will try to fix my car again in the future, I just know when its time to give up now.
Thanks to everyone who gave me advice.
