As far as I know, Ford Racing has not released the 3.5L Ecoboost Controls Pak as yet. I have spent a lot of my free time working on wiring for 3.5L EB with 6R80. I have one vehicle running, performs well just like when it was in the 2011 F150, and I have done harnesses for 2 other swaps that are not yet complete. (These swaps always take more $$$ than people expect, and you need a lot of custom-made items besides just the wiring harnesses. P/S solution, custom intercooler, driveshaft, mounts, BIG radiator, trans cooler, air intake system, etc. etc.)
I am now working on wiring for 2 different 5.0L/6R80 projects. The first swap was into a 93 Fox body and it started and ran but not on the road yet as owner has decided to get the back-half done and it is in a shop for that. Second project has the engine and trans installed but he is having trouble finding all the factory harnesses I need. (TIP: buy a rolled or wreck 2011-2015 F150 that lot drives, then you will have everything you need to make the 3.5L or the 5.0L run with a 6R80, and in the long run it is way cheaper as you can sell a lot of the parts you do not need.)
