MikeAg, My 2000 FD was pre-wired for a fan, it seems strange that your 2000 isn't. I'm not positive, but I think , in our case, the power was picked up from the
lighting circuit over the side dinette. It was not possible to see the wires until the vent was removed completely and they were tucked into the foam insulation between
fiberglass and carpet on the side of the vent opening closest to the side dinette.
If they really are not in existence, then the way I'd do it is to remove the existing vent so the edge of the carpet is exposed. Use a straightened coat hanger which is long enough to reach into the cabinet over the dinette. Very carefully push the end through the foam insulation between the carpet and roof, starting with the side of the vent opening closest to the dinette. Once it has appeared inside the cabinet, fold the end of the hanger (in the vent opening) at about a 45 degree angle approx. 2 1/2" from the end. Then fold it back again so there is about a 1/4" jog in the wire. Now fold the remaining part of the same end of the wire so it forms a fairly tight hook to hold the 2 strands of
electrical wire. The end of the hook should line up with the straight part of the hanger so the hook will not catch on the foam insulation. The
electrical wire should be placed through the hook, doubled over so a 3" loop is formed. The loop should be squeezed tightly so it will follow the hanger without a lot of resistance. Start wrapping
electrical tape around the wires overlapping as you go, until you have covered about 3" of the coat hanger. If memory serves, one length each of black and white #14 wire was used. The lengths should be long enough to reach from the vent opening to the splice location plus about 6" extra. The fun begins! Start pulling the hanger inside the cabinet bending it as necessary so it doesn't get caught in the cabinet. Stop when the electrical wire appears.
At this point, the difficult part has been accomplished.
The job is easier if you have someone to assist by feeding the electric wires as you pull on the coat hanger.
Congratulate yourself, follow the directions that come with the Fantastic Fan and connect the wires in the cabinet, and you'll be done. Check the
Casita wiring diagram to locate which wires to splice.
Enjoy the mod process!
