So here are the steps:

1. Plug in OBD2 device
2. Download Carista and pay for a 1 week subscription.
3. Open the app
4. Click on "customize"
5. It will take a minute or 2 to read the ECU.
6. After the meter hits 100%, click on "lights"
7. Enter my settings.

Make sure your auto headlights are on.
I strongly recommend writing your settings down before making changes.
