I had to replace my stair gearbox as well. Once removed, the old style motor did not fit with the new style/amazon box. No worries, ordered the motor from the same supplier, fits fine.

I have one weirdness though. My light comes on when the step is retracted and OFF when it's extended. Checked the wiring, all as per diagrams. Step switch in door fram works as advertised. I.e. door open steps out and door closed steps in. The lock switch by the door works as well. Flip it on and the steps stay out, unless you start the coach, then they retract.

No idea about the light.
