Do you have attic access? I located a rafter where I wanted to hang the screen, did some measurements and simply cut out the opening with a saber saw. I finished the hole by glueing corner trim around the opening. It looked nice, you can't see the hole until you are right under it. For the wires, I mounted the electrical box on a support beam in the attic. I then found a wall switch that I wasn't using, and connected the wall plate there. You can bypass that if you get a remote control with the screen. The sensor simply mounts to the bottom of the screen casing with adhesive, and connects to the electric box that came with the screen. All of the electrical stuff is very simple to connect and the diagrams were easy to decipher. The hardest part for me was manuevering the screen into place in the attic. I had to squeeze it under an a/c duct, and barely made it. All in all it took me and a friend an afternoon to get it up and running. I am NOT a handy person either. By the way, I used a 119" diaganol Stewart Grayhawk Microperf screen. (It is for sale in the avs classifieds above!)
