Where did you pull the wires from to power the vent? I also have a 174BH, great little trailer. I pulled the wire from the LED light next to the vent but it doesn't seem to run the fan. I'm only connected to battery power at the moment, so don't know if I need shore power.
Thanks in advance.

The other tricky part is getting the holes for the mount screws and the roof vent gear crank to all allign. Other than that it only took maybe 30 minutes per fan. They made a huge difference in airflow. On high the one fan pulls enough air to make the other start circulating. I also noticed how much air was leaking via the wall mount ac unit. Some pipe insulation and aluminum tape seemed to do the trick.
