       CAn I install a smoke unit into a DCC engine??   I was wondering if this was ever tried before?

You can, but it would not be a good idea.  DCC requires clean track.  Smoke units dirty track rapidly.  To make the DCC operate, you'd have to be cleaning track constantly.

Yes you can.  
If your engine has a circuit board in it , get the wiring diagram . Usually the schematic shows which pins to hook up to . Look for the pin numbers on the diagram to match up the pin holes on the board and solder the wires from the smoke unit to them . and don't over dose on the solder , and keep it off other solder pad contacts  to avoid shorting it out .  Tin the wires first , before putting them in to the circuit board .
I am not telling you how to solder , but if you have not soldered before , these tips will help . I learn the had way .
Test the smoke unit out of the engine first and don't forget to add the oil , so as not to  burn it out .
Good Luck
