That should work, are the following statements correct?
After I reinstall the harness, to perform E7 I would look for 3.0 to 5.0 ohms between wires 925 and 912 using the diagram from post #5? I have have a picture of pinout for a 92 F150 that shows both 1 and 12 as a 361 Red.
No ground to battery, continuity, on 925 and 912.
Key on, more than 10.5 volts to 912 on the truck or pcm side of connector.
Kind of need someone to rewrite these tests for a dummy like me with out a breakout box or rotunda. Unsure how to do E1 or E2

Each wire is between 0.6 to 0.7 ohms as measured by my el cheap o meter so I feel like I can trust the harness once reinstalled. @subford @ZombieF150 @vjsimone @Mark Kovalsky @torq'ta 5 8

Wet from rain now. 12.55 to red and white/red with key on truck side. No continuity to ground anywhere on the harness to transmission side. Connected harness back. Ran koeo seemed to get a quick flash on the od light then 111 followed by 624 so I disconnected the battery.
Went back out, forgot my phone. Reconnected battery. Tried flashing. Got 111 and 512 I think. Started it and did koeo with engine cold and got 311. Tied koeo and just saw 111. Maybe I need to drive it to get the code again but it is raining too hard for me to get under and get the harness secured back in place.

your deeper than my hip-waders can go on this, your 624(electronic pressure control solenoid circuit fault) was there before you took harness off? or because you removed and testing harness? and 512 Keep Alive Memory (KAM) test failure, wonder if warming up and going through gears with emergency brake on and foot on brake pedal so you wouldnt have to button everything up?

Going to try to button it up this morning, I have a quick 40 mile trip. If it goes up and down my street decently then I am going to send it, see how it does and look at codes when I get back. Going to blame 512 for trying to clear codes during koeo before disconnecting battery. 624 was present before removing harness and an open circuit might have caused it. Maybe I get lucky and cleaning and reassembling everything corrected it. I think 624 is the cause of my hard 1-2 shift.

60 miles down and it is shifting so smooth you have to watch the tach to even notice. All 4 are working. Hopefully y’all don’t bust my bubble and tell me I have a ways to go before a code would reset. Who’s got the most economical shift kit for a stock E4od?
