Mysterious rich LTFT's

I am very curious to see if addressing the MAF harness will fix the issue; problem is I'm working out of town, and not at my car Reading the TSB's for this issue, they indicated it was the black ground wire that caused all these issues. Should this be the only wire I do? Or would all the wires need to be cut, stripped, and repinned?

You are right about the trims but what i noticed with my car is that ir learns the trims within 2 miles of driving. And they will slightly level out within the next 10 but its basically spot on within 2 mile. I tried disconnecting the battery and re flashes and it still learns it that fast.

Yes ltft are based off stft but when my ltft are -.94 with stft -17 the car should pick that up pretty quick. 2 day it learned some and went to -10 ltft and then out of no where it went to -.16 ltft like if some how it got reset? Idk whats going on there. Going to check for leaks again and if nothing try adjusting the maf cal a bit.

And yes i read it was the black wire also. I ended up with a new pig tail so i cut and spliced all new wires. Now when i wiggle the wires i get nothing to happen on the ap which is good. I also have a 2nd maf sensor i may try out and see what happens.
