UPDATE:
OK all. I was able to follow the instructions in the OP and successfully added cruise control to my 2022 AWD 150. I downloaded the free version of FORscan, as well as the free 2 month license. I purchased the recommended OBD adapter and found a steering wheel from a wrecked 2020 Transit at a wrecking yard in Ohio. I believe I found it by running a search on car-parts.com. I called the wrecking yard to make sure it was still available, and then placed the order.
Steering wheel: $85 shipped (excellent condition, no airbag)
OBDII adapter: $60
Time to install: free - had a light day at work
Some info left out of the OP:
You have to click "write" after making your change. Then hit the "stop" key, and then go back in and check to make sure that the change was made. Your headlights will blink a couple of times after you hit "write".
There were a ton of options when turning on cruise control. The first one just says "cruise control", but there are a bunch of options having to do with adaptive this and that. I just wanted normal cruise control so I selected the first option. I don't know if my vehicle is capable of the adaptive features, it does have the stupid lane avoidance stuff which I usually keep off anyway, so I am guessing it is, but I didn't want to mess with stuff too much, I just wanted regular cruise control.
I did have to pop the airbag out of my old wheel and transfer it to the new wheel. This was not difficult once I figured out how the clips work. I recommend a small handheld mirror and flashlight to shine into the release ports in the back of the wheel so you can see what you are doing, as well as disconnect the negative battery terminal before doing this.
FYI I did NOT have the option of ordering this vehicle with anything LESS than the expensive adaptive cruise system, so the fact that I was able to avoid the high tech stuff while doing this is a big bonus. Shame on Ford for not giving folks the options on the technology that is truly available with these vehicles. Why, it's almost like they want to swindle us out of more money. Jeez, who woulda thought?
I was able to do this even though I am not an IT type of guy. I don't know how to code a thing.
Good luck all, and thanks again to all of you guys who take the time to post this stuff online. I drive a lot of freeway miles, this is a real game-changer for me.
