Do you know what circuit it was?

It was headed towards the evap set up above the spare tire.
I am assuming that it was power for the "pump" on that.
If I recall right there was a red lead with yellow stripe, and a pink-violet with white stripe.
I was following the bigger diameter vacuum hoses running from the topside of gas tank.
Saw the suspect area of the small corrugated conduit before I got the spare tire down.
Dropped that so I could get better access and saw that it did lead to the contraption above the spare.

Sounds good to me
I had not really looked into diagrams for the set up or wiring schematics at all.
I was still thinking it was the fuel cap until I crawled underneath and found the broken wires.

Driving in this morning, still no codes showing but looking at real time information shows that EVAP testing incomplete.
It was showing code P0446 almost instantly before after I would clear it.
Still have fingers crossed and hope it was the wiring issue that caused the codes.

I think you can relax, everything you found and fixed points to the trouble code you were getting.

I'd approach it with a guarded level of optimism.
The repair to the wiring should address the P0446 DTC, assuming that there are no other electrical circuit faults. That particular code would have been an immediate failure as the integrity of the electrical circuit is a continuously monitored item.
What remains to be seen is whether or not the EVAP system can successfully execute its leak testing monitor which previously resulted in the P0442 DTC. That DTC may have been related to or it may have been coincidental to the electrical circuit fault. You'll just need to wait for the EVAP monitor to execute which may take hours, days, weeks, or even months before it runs. It's entry criteria is pretty narrow so the totality of conditions needs to be "just right" before the test will be run and you'll just have to be patient.
FWIW, when I joined this thread, I was fixated on the P0442 code and the P0446 seemed to have completely missed my attention, even with it being in bold print in the thread's title. Sometimes, I think I'm getting old....
