Hi Robert
My coach is older than yours and not likely the same but when looking for the controller it should be mounted close to the front of the awning area in the coach.
If you look up under the awning from below you will see the mounting blocks where the awning attaches to the wall there are three of these blocks between the awning and the wall , locate the front most one and then go inside the coach to the same relative area and open your cabinets you will be looking for the bolts usually three that are holding the mounting block to the wall the bolts will be holding an other plate on the inside ( backer plate) there should be a wiring cable come through that plate as well this is the control cable for the awning motor .
If you follow the cable it should lead you to the contoller.
In my coach when you look at the end of the cabinet above the pass seat there is a manual button set for the awning if you go inside that cabinet you will find a false wall section in the end of the cabinet and the controller is behind that false wall beside the switch.
Hope this helps
Eric
