Not sure what you mean by "should I add a cut in box " By code your switch needs to be in a box, you can add a box if that's what you mean by cut in. White wires are not associated with a switch, the switch interrupts the run of a black wire. You have to figure out which black is hot and which one continues on to the switch, those are the 2 connected to the switch

Mobile homes often use switches and receptacle devices that are modular and do not need outlet boxes.
If you add new, and are unable to find the modular style devices, and use standard devices, then back boxes will be needed.
