Why does the speedo send the demand? Is it an analog or digital (on/off) signal?

That's just how the did engineers deemed it appropriate I guess. Manual air the request for a.c. is analog. Automatic air it's digital.

Im a little late answering this. You can avoid changing out the speedo bezel if you either find a fx4 cluster that came from a truck with auto air or convince ford to reprogram an xlt cluster with the programming from a lariat or fx4 with EATC.

If you swap to a Lariat cluster you will want to swap the bezel out because the lariat cluster's buttons are mounted to the bezel

Bad as.s write up Thisguy'.

Collecting all the parts now to upgrade my '06 XLT. Best score has been a Lariat cluster with mileage just a couple thousand ahead of mine, just gotta wait to catch up and swap. I haven't pulled the cluster apart yet, was wondering if the 'Lariat' logo in the center is a knock-out thus allowing the gear selection display to install in its place. Do you know?

Yes. It just pops right off.

Where is the electronic blower motor speed controller located? Found a late model salvage company in Portland, Oregon that I want to contact for these components you've listed for the swap. The other tough part I'm looking for is the Lariat stereo/climate bezel for a column shifted truck.

(Found a bezel in tonights parts quest lol. EATC control module, blower speed controller and interior sensor tube is the last of my search. Is $99 reasonable for the EATC?)

Thisguyuknow

yes and no. they vary in price. I actually got mine off ebay for 15 bucks. but I didn't 70 on.the console shift style bezel. the blower speed controller is located behind the glove box in the same spot where the blower resistor would be for a manual system. I have an extra motocraft tube and two sensor you can have for 30 shipped if you want. It's still in the box and everything.

hey, i just tried a lariat cluster in my truck, the truck had an auto setup in it already from a cab swap i did so the last part was the cluster for the ac to work.. everything in the ac system is tested and working but when i put the new cluster in the ac still did not work.. would i need to remove and re install the battery for it to realize the change?
the wrecker and dealer both told me it had to be the exact cluster matching the engineering number to work? is this true?

thanks

It has to do with the temperature display that appears in the clusters information display. The "auto climate" feature was offered on the F150's that had this type of cluster (i.e. Lariat, King ranch, and other "higher end" F150 option packages). Adding it to a F150 that did not come with this package makes it harder to accomplish; we just have to understand and accept that it requires some additional "engineering" to make it all work.

Also as 94f1504x4I6 asks, the PCM/ECU is "knowing" of this feature as well. Simply putting in a cluster from one of the models that had the auto climate feature will not fix that. The PCM/ECU would need to be reflashed.
