The CPU is back behind the cluster of wires, mounted to the wall, making it difficult to see. Keep looking, it is more than likely there. Removing the pilot seat makes the job a lot easier. As far as programming, Rick told me that the two new ones I received were updated with the newest updates. The ones on E-bay, from what I was told, are programmed for trucks and would be difficult to adapt to our motorhomes. Might ask Rick if that is something that might be possible. Good luck!
