Question on Wurlitzer Satellite II

Hi
I am trying to hook up a Satellite II to my Wurlitzer 3600 Americana. I
think I have the right wires connected and it is plugged into the stepper
unit. However, when I put coins in the satellite, the selector switches do
not seem to register. When I play a record on the jukebox, there is no
sound out of the satellite. Everything on the satellite lights up and in
fact as far as I can tell, it has never been used.
Any suggestions or tips are greatly appreciated.

Thanks
