I'm still deployed and will not be home until Sept. But as soon as I get home we are heading out somewhere. The two boxes with the red light may be something that someone else added to the coach. I will defiantly look at it closer once home to see what system I have on it. I believe I still have you email and will see if the manual I have is the same one you have. If not I will send it out to you if the internet will support it.
Take care
Jim
