I've had the F2P on each of my last four bikes, and love it! I have two different garages, plus my shop, so with three garage doors, the F2P comes in handy. First of all, the square black "hockey puck looking module" attaches to your high beam headlight wires. Using the little blue "Posi-tap connector" plastic splicer deals, splice one of the two module wires to one of your high beam wires, and the other module wire to your other high beam wire. If you are not sure what color your high beam wires are, there is a chart on the F2P web site that lists most major bike makes and models. Then disconnect the existing garage door opener switch box mounted on your garage wall, and replace it with the F2P switch box. You can save your old wall box for later use, or you can discard it. I've still got my old wall box from 5 years ago, and may yet find a use for it. Anyhow, that's all there is to it. The F2P does not interfere with high beam operation in any way. To open your garage door, simply click your high beams on and off twice in succession, and the door should open. Hi-lo, hi-lo, door open.
As a footnote, I should add that on some garage doors, the current from the wall switch box needs a boost. If so, you may need to plug in a booster. These are available from the F2P folks, or you may have one lying around your house. Of my three garage doors, one needed a booster, and I used an old ac/dc power supply from an old calculator. I forget the specs just now, but they are listed on the web site. Something like 110 vac to 5 vdc.
You will love it! And if you don't, it should be very easy to sell. The F2P device also has an iphone/droid app too, but I have not yet tried that. Open your garage dor with you iphone...how about that!
