FINAL UPDATE!!!! I needed to find a way to connect and disconnect the 12 volt power and furnace connections. I purchased a 12" 4 pair flat trailer wire extender. I cut the extender and wired each side to the wires I previously cut. I also made a base for the thermostat. I plugged everything in, configured the thermostat, set the temp and she came to life. Boy is quiet... I set the heat pump for heat and at first I was thinking if this is as warm as it gets... I'll be using the furnace... It wan't putting out a lot of heat then the compressor kicked in... The heat pup was throwing out some nice warm air. In short order it was really warm in the pup. I've not had a chance to try the AC side, but if it works as well as the heat pump, I'll be warm in the cold temps, and cool in the hot temps. This was a LOT more work and effort because of the style unit I got, but in the end I'll enjoy it as it will make camping even more enjoyable.
