SnowEx Spreader Controller # F50607. This is just the controller.
There is also a similar controller that has a vibrate button, known as F50574.
This control is used with the non-1 tailgate spreaders SP-575X and SP-1075X. It has a single knob, a digital number display, a button for the blast function, start/stop and on and off.
This plugs into data cable # F50578 and runs to the spreader module F50576. If you need all the wiring we have a kit F50869.
