why are you confused?
I loosened the dash and installed the heater core and bolted dash back. I however didn’t buy lines fittings and hoses for the under hood part.

It's kind of an odd post. Reporting a few random things. Good luck with it though.

or what likely caused it to stop working by removing dash
I know there’s a sensor near brake fluid that often affects cruise bc a previous F150 I had to change sensor

Had absolutely no issues with my cruise control prior to pulling my dash and installing heater core.
I will hook hoses up later.

others have posted online that cruise stopped after pulling dash for heater core. I only slide passenger side out as much as possible to do the job
anything I could have unplugged to stop cruise from working? I know there’s a sensor by brake fluid but I haven’t touched that.

There is a bunch of connectors down there on the left side of the dash
One of them is unplugged coming from the steering column clockspring most likely
Check the codes

My money is on a busted clock spring (aka sliding contact). Common issue when rookies try to DIY. Seen it time and time again. Did it myself when I was still wet behind the ears.

So, is there a technique or pointers for those that are inexperienced with them? Just trying to soak up knowledge here...

Yes,
You simply unplug the clockspring before you start the work and then do not let it rotate while out
You need to trace the wires from the clockspring down to their connectors (2)
If they are plugged in, you probably broke the sliding contact inside
Code test to verify

I always wrap the driver seatbelt around the steering wheel to prevent it from turning while the column is disconnected during these type of jobs. That's how 99.9% what happens when the column is moved/removed.
