Welcome. I just joined recently with a 2015 XLT EL. There is a "Forscan" area of the forum for programming. I have used it already to activate a self-installed Trailer Brake Controller, and to keep my fog lights from turning off when I activate the high-beams.
Next up. Turning off the Key Chime (doo doo doo, doo doo doo, doo doo doo). Then enable the remote start.
