Why would the pin in the 1-2 accumulator be out of place?

1-2 solenoid not turning on? It's on during 1st and 4th but not 2nd or 3rd.

The 1-2 accumulator is used during the 1->2 shift.
As mentioned, the most likely cause is the 1-2 Solenoid is disconnected, either because you didn't fully plug it in, its electrical tabs got broken or the new harness is defective.
