Yes, if this is the unit that you have on your roof then the only wires that are feeding the air conditioner are the 120VAC wires that are fed in a sleeve. You can remove the inner shroud of the unit and see where the wires are feeding into the roof. There is no specific wiring diagram for your unit that I can find or anything that I have on file. These should be the only wires that are in the roof near your Air Conditioner. Hope this helps. Let me know what you find out.
