Installed the Maxxfan Maxxair Delux yesterday in the rear bedroom area of our Lexi. As Mr clemens noted, it was pre-wired, and install was as easy as just cutting and splicing the fan wires into the rig's wire. Works perfectly.
Now have two really decent fans, one can pull air in while the other pulls air out creating a nice air flow. Really does work.
Took the original 3 speed fan that was mounted in the front living area and installed it in place of the little single speed fan in the bathroom.
