I would guess that the wiring is there, but not the switches. I have seen one with a panel where my switches are but it is blank. However, there was a plug on the back of it. Check out a unit with the hard top and see if there is a switch panel to the right of the steering column at the bottom of the dash. Is so, compare it to yours and see if you have the wiring hooked into it.
This is the vehicle I just committed to buy. Think it will need a LITTLE work before putting it on the road. It showes the back of the hard top panel to the right of the steering column area.
If you have the wiring, you should be able to get the switch panel from a salvage yard.
