Thanks Doug and Fred. This is what I tought, all the functions of the furnace should not be affected and everything seems to work as before. I do not know which and where I would connect the new T-stat directly to the furnace.
The living room T-Stat ONLY will control the ON/OFF of the furnace, the new room T-stat is only a heat on/off to fool the front one, like a check point in line saying "hey wait until it is cold here to kick on".
I do have two factory T-stat installed in the MH, one in the living room and one in the room. The living room operates the Front AC and/or fan and the furnace. The room T stat control the Rear AC and/or fan only, not the furnace.
The rear one does not control the furnace but all the wires are connected to it like the front one. I wish I could have used this rear one to control the furnace also but really do not know how I could do it. Maybe it would be easier to try to connect the rear one to control the furnace also?
As for the very tiny wires that connects in the T-stats, I did not see where they connect to. They are different size than the one connecting at the furnace plug. The furnace one are normal gauge wires like 16 or 18 gauge I guess. If I could find the tiny one in the basement or somewhere, maybe I could Tap these one to operate from the rear instead of using a new T-stat.
Any advices on this is appreciated.
