The link you posted was for a Mustang Coyote engine...the engine will work but the transmission is a 2WD.
I would suggest you do a ton of research before moving forward with a Coyote swap. There is some info here and there is a Facebook group called Early Coyote swapped Broncos that also has some good information. Read everything you can and suggest looking at the build threads of a few done here...lot of good info on what works and what caused issues.
Get very familiar with the generations of engines from Mustang's and F150's and which transmissions/control packs go with which generation.
Would also suggest understanding which vendors offer what products for the swap (BC, Kincer/Krawlers Edge, Power By The Hour, etc). Try to stick with one vendor as much as possible...the motor mounts you use determine the position the motor sits which can impact the fitment of your headers, serpentine, starter, oil filter, crossmember, etc.
I am doing a Gen 2 Mustang with a 6R80 4x4 trans from a 2016 F150. In the early stages but have tried to buy as many parts now due to long backorders/lead times. It is an expensive swap but almost everything Bronco can get expensive.
I know using the existing computer can be done but it takes somebody changing the PCM to turn off the PATS (Passive Anti-Theft System)...the computer looks for all parts of the system in order to function...if they arent all present then it wont function correctly as an anti theft deterrent. I went with a Ford Control Pack in lieu of using the factory stuff.
