Where is my air charge temperature sensor located?

Yes, that is a 7.5L gas engine in your truck. The photos confirm the sticker under the hood for belt routing is correct for the truck.
Next question is why are you asking about the ACT sensor location?

While I was driving from New York to Ohio. About an 2 hours into the 10 hour drive, my CEL came on then the about 10 minutes the engine grew louder. I decided to pull over, as I am coming to a stop the truck is idling very rough I felt like it would die any moment so I get to a gas station I turn off the truck. I turn the truck back on and everything seems right as rain. I drove to Ohio without any other issues. I just got a Code Reader today and the codes “114” and “116” appear so I figured why not replace the ACT.

What tests were you running? Key On Engine Off (KOEO)/Stored Code display or the Key On Engine Running (KOER)?
In either case the engine has to be up to operating temperature before running them, otherwise you will trigger false codes.
Highly suggest to run Key On Engine Off (KOEO) tests/Stored Code display first.

Did you get the same Code 111 System Pass for Stored Codes? If you did not leave the code reader on long enough the CM codes were not displayed.
There are two parts to running the KOEO tests and Stored Code display. The first to flash out are any failures during the KOEO tests. If there were no issue flagged you will get Code 111 (twice). Once the KOEO tests and display are completed the computer will send out a single separator flash, which many code reader interpret as Code 10. Then any codes from Continuous Memory are displayed. If there are no Stored Codes you will see Code 111 System Pass displayed (twice)
If you did not "goose" the throttle at the correct time you can falsely trigger this code.

Based on your results I would leave the ACT in place. No sense bringing in a new variable.
I am more concerned you previously had an active Check Engine Light, but nothing in CM.

I have to to agree with rla about the check engine light coming on but no stored codes in the system especially with all the faulty/ failing computer issues people seem to be having.

I do not think he understands about the Continuous Memory (CM) codes and he is just doing the KOEO electrical test and the KOER solenoid/relay test.
The Key On Engine Off electrical and Engine Running solenoid/relay Self-Tests detect faults that are present at the time of testing. Faults that occur only when the vehicle is operating or intermittent faults that have occurred in the last 80 warm-up cycles are detected during Continuous Self-Test, they are stored in Continuous Memory and displayed after the Key On Engine Off Self-Test is over and a separator pulse code (10) out put.
A single 1/2 second separator pulse is issued 6-9 seconds after the last Key On Engine Off DTC is over. Then, 6-9 seconds after the single 1/2 second separator pulse, the Continuous Memory DTCs will be issued.

That would be my guess.
