P0113 IAT High Voltage in 2016 TC 2.5

[i86hotdogs]

Forgive me for the sporatic questions, I pulled a P0113 code on my 2016 TC with the 2.5. Is the IAT sensor integrated in the MAF sensor located on the airbox? I only ask because there are only 4 wires going to the MAF connector. On most MAF sensors with the IAT integrated, there are 6 wires going to it. 

 

I replaced the MAF sensor back in January to correct a MAF sensor code. So the sensor is fairly new, and I've only put a few hundred miles on it since. I did notice some fraying on the light purlple with dark purple striped wire. So that may be the root cause as well. I just want to confirm before I do some wiring. I haven't been able to find any diagrams for this piece. Knowing which wires go to what would be beneficial. I bought a Motorcraft wiring kit yesterday, and just my luck: the connector does not fit on the MAF sensor. There are hundreds of these wires in the junkyard, from similar Fords: Focus, Fusion, Escape, etc. But all of them have 6 wires going to them, and only two wires match in color: yellow with purple stripe and light purple with dark purple stripe. 

 

Any direction would be greatly appreciated in this. The van runs, but will struggle to start when cold. And I know the van will run lean with this code active, so I'm trying to fix the issue ASAP as possible. Thanks all!

Here's the wiring diagram.

Don, you're a saint for this. As suspected, the purple wire is the IAT wire, and that's what was frayed. I took the pigtail from the fusion at the junkyard and wired it up with no issue. Thanks again for the help!
