Hello, its a real long shot attempting to fit a new board into an old furnace with different wire connects... in the field we never take that chance.... you will be best off getting the correct control board from a reputable dealer with the identical wire connections.

I have never seen that in my 50 year career much of it with trane, I would give trane a call and as for wiring instructions in this case, good luck with it
