OBD2 Upgrades

[Hawaiianphatboy]

Aloha, new owner of a 2025 Explorer ST-Line. I just recently purchased an ODB2 scanner and was wondering what mods people are doing with theirs. The only thing I could see that I could get to work of any real change was changing the rear brake lights to turn signals as well. Other small things like making the fog lights active when using the high beams, turning off the auto head light selector and stuff like that. Was curious as to what other things people have done to theirs. Aloha and mahalo
