I'd have to review the wiring diagram but off hand just reading all the codes you posted you might have simply missed a ground on the upper intake? when putting it together.
Either that or you missed more then one circuit, have a hand full of bad sensors, or a damaged harness. Oh and forgot the vac line to the map sensor.
How it passed KOEO test?

In my testing I pulled different things just see if it changed things, so I think I had a lot of false codes
pulled the cable off the battery ,system cleared. New codes
111,10,512
111 system pass koeo
10 test over
(cm)
512 keep alive memory test failure Think it's because the battery was unhooked
Test Drive
111,10,128,212
111 system pass koeo
10 test over
(cm)
128 MAP sensor /vacuum hose disconnected or damaged
212 loss of ignition diagnostic monitor signal/Spout circuit grounded
Changed MAP
pulled the cable off the battery ,system cleared. New codes
111,10,512
111 system pass koeo
10 test over
(cm)
512 keep alive memory test failure Think it's because the battery was unhooked
Test Drive
111,10,128,212
111 system pass koeo

(cm)
128 MAP sensor /vacuum hose disconnected or damaged
212 loss of ignition diagnostic monitor signal/Spout circuit grounded
So I thank the ignition system is failing (212) the truck falls on its face. loss of vac code (128)
What do I test to figure out what the 212 is?

Check the spout connector, its a little gray plug by the brake booster. If it is plugged up then follow the wires back both ways and check for damage. If the spout connector is grounding out somewhere then it would not advance the timing which would cause the low vac reading. The timing not advancing would also cause it to fall on its face during acc.

That's bad.... even in the same year there may be wiring pinout differences between truck models, you need to put the F250 wiring back on the motor.. I bet all your issues will immediately disappear.
