I realize you have 4 operating tracks and presumably you are using 8 ACC ports.
Focusing on the pics you posted which using ACC5 (for unload) and ACC6 (for uncouple). So apparently now you press "ACT" for ACC6 and uncouple works for one operating track. But you press "ACT" for ACC5 and you get no operation for that same operating track. Is that correct?
Just focusing on ACC5. The only change in wiring is you moved the connection that was to terminal 2 over to terminal 1. The wire(s) going to terminal IN has not changed.
Are you confident you are pressing the "ACT" button for ACC5? Do you hear a faint relay "click" from the AIU case when you press "ACT" and then another "click" when you release "ACT"? I realize there are dozens of relays inside the AIU so you can't tell which relay is clicking on/off but you should at least hear a click.
