[QUOTE=Luckeduck;663529]Yes it is the one with the nozzle.. I'm not sure if it's powering up because the switch is kinda stiff and it doesn't seem like it flips all the way over.. So your saying that the system has to be powered on via switch next to the gauge to get a reading?
On most toy haulers there is a switch inside that sends power to the outside switch next to the gauge. In my model, I turn on my inside switch located on the wall next to stove and then I have power at the outside switch and gauge. Mine also has a timer built in that only allows power to be on for about 10 min.
Based on your pictures I still think that is an outside cold water faucet and a TV mount. I would just turn it on and see what comes out, water or propane. Just Don't have an open flame close by. Safest way would be to hook up to city water purge air from lines by running faucets inside. Turn off propane at tanks. Open mystery valve and see if water flows out.
