Scully,
The kit comes with 1 toggle switch. I didn't like the look so I did not use it. The switch wiring is the least of my worries. Keeping the controlers out of the mud soup is more important to me for now.
hapynzap,
Most kits have it wired so the fans come on with the A/C compressor.

For those asking.................
Our kit incorporates parts from over a dozen different manufacturers, copies *no* existing design or kit, allows the use of any temperature of thermostat, features dual 16" fans with fully enclosed housings to prevent injury and dual independent and adjustable controllers, with proper high-grade relays & fusing, no cheap stuff, and at a price less than other kits.
Our dual 16" fans take literally 100% of the width of the fin surface area, and the vast majority of the height, too, for maximum capacity & cooling efficiency. This is doubly important in the late-model F-150 & Expedition, as the A/C condensor is huge, and it is in front of the radiator (as usual), but in this case there is also a very significant distance between the A/C condensor and the radiator. So you need all the cooling power possible, and need to use as much of the radiator's surface area as possible for even temperatures & cooling as well as best A/C function, as that's a lot of area and space to pull airflow thru in these vehicles.
Everyone has their favorites, to be sure. And the last thing we wanted to do was make a fan kit, we'd much rather have just sold some other manufacturers kit and not have had to take months out of our schedules to come up with a kit design, do all the testing, sourcing, more testing, etc., but nobody else had one that met our requirements, so we basically had no choice.
Most commercial kits use lower-grade raw components, lighter grade motors, straight exposed fan blades, etc., none of which is acceptable to us. Bang for the buck, our kit does a great job in raw component quality and effectiveness, and it's been tested in 107, 111, 115 & 117 degrees (F) out in the desert SouthWest, as well as in the humid semi-jungles of south Florida. In the high heat testing we saw coolant temperatures reduced by as much as 35+ degrees (and that's with the stock 192 degree thermostat) in a worst-case scenario as compared to the stock factory setup in those conditions (111+ degrees ambient), tested by idling in gear for an hour with the emergency brake set & the A/C on full blast.
Of course, the power gains won't vary much from one electric fan kit to the next, as they all come from the exact same thing, removing the parasitic losses caused by the dead mass of the factory 10+ lb. mechanical fan having to constantly be accelerated up to engine rpms along with everything else. So they average out at about 15 Hp rear wheel in the late-model F-150, and also generally show anywhere from 1.0 to as much as 2.5 more mpg, depending on how the vehicle is driven.
If anyone would like details, pricing, etc., please give us a shout, our contact info is just below.
And by the way, gang..........Happy New Year!
