no problem. If you can post a picture of the wiring at your thermostat (pull off the cover) so that you / we can see the terminal and wire connections. We might get an idea of what your next steps might be... ie. chasing wiring or otherwise. According to some dometic wiring, there should be 6 wires at the thermostat. Less may mean that some "mods" were done previously instead of running additional cabling.... and those "mods" may not have been as "expected".
