Need Help with used Fantastic Vent

Hi All;
I am ready to install the used Fantastic Vent Model 2000DMB which I bought in the spring.
The Power red/black and negative white are nicely labeled. So no problem there.
It comes with two orange cables. When I short them the unit will open and the fan will run on the selected speed. So I figure it's working.
The trouble is what kind of switch should I put between the orange wires and where do you mount it. I thought that all the controls would be on the unit itself. I will try to attach a picture in this message. If I can't figure it out please check in my album.
thanks
