Is it just in the pigtail area of the harness ? Your best bet is just a new pigtail assembly off eBay and do the harness repair yourself. Re-wrap the harness with electrical tape when you're done.

I’m not sure if I just need the pigtail I just want to be able inspect the harness. Here are the codes that pop up.
Po1747 pressure control short circuit
Po750 shift solenoid A
Po755 shift solenoid B
Po743 torque converter
And both rear O2 sensors.
All of these codes came on at the same time.

Have you gotten under there and looked ? Sounds like an animal chewed through it or it got damaged on an exhaust pipe. If you want a whole harness you're gonna have to scavenge some from a scrapyard.

Yes I got underneath and found both my rear o2 sensor wires are completely broken that’s all I can see visually for now. So I’m guessing I need to inspect the whole harness. By what I see underneath it looks like the driver side rear o2 sensor somehow got wrapped up in the front drive line I found some wires wrapped around it.
