The heater box is the galvanized sheet metal enclosure that houses the blower motor, the heat exchanger/burner can and all the electric wiring/circuitry for the furnace. The thermostat is separate. The supply ducts come out of the box on the interior of your MH. If your furnace is mounted horizontally, remove the exterior cover ((4 screws secure it. Its the cover with the air intake/exhaust on it) the multi point house connector penetrates the sheet metal enclosure on the left side in the upper 1/3 of the box. I hope you have small hands. If the yellow ground wire is burned you'll see it right away. If the ground connection is bad inside the multi point terminal, you'll have to separate the multi point connector to see that. I can email you a pic of mine if you can't locate what I am talking about. No need to take apart the furnace other than remove the outside cover for this fix.
