Welcome to the forums ORSAG 🍻
Yet another great Kirk Olsson creation. Improvements have been made to the original and the one I've been flying ever since it's release is this one:
https://flyawaysimulation.com/downloads/files/2623/fsx-lockheed-martin-f-16-fighting-falcon/
Needless to say you take the one at the bottom of the page, uncharacteristically both files share the same name...
This file is complete, ABs work and everything else you can think of. For your future reference, if you ever come across another file developed by this team, you can bank on it. They're the real deal.
Now to the installation, it's pretty straight forward:
After having extracted the contents of f-16c_haf_v3.zip you'll be left with a .txt file and a folder: F-16C_HAF_v3... place this folder as is into your fs9 / aircraft directory.
Next, open this F-16C_HAF_v3 folder.
Amongst the many folders and other files you'll find an 'effects' folder (probably at the top of the list) --- open this 'effects' folder and copy and paste all of its contents into your fs9 / effects directory - there should be 19 effects total.
Next step: Open the 'gauges' folder (also on top of the list) and copy and paste all of its contents (including the subfolder 'Falcon') into your fs9 / gauges directory - there should be 55 items total (including the 'Falcon' folder). Your done.
Have fun 😀
