Hey all! Well, it appears we can add auto rain sensing wipers to the list of things AlfaOBD can do. Below is a list of parts needed and settings to enable in Alfa.
YOU WILL HAVE TO HAVE THE UPGRADED MIRROR HARNESS IN ORDER FOR THIS TO WORK.
Those who have performed the MTC to ATC conversion and installed the correct harness for the humidity sensor behind the mirror should have the harness already. It is the extra plug leftover after the install.
Link to @Mpgrimm2 post regarding information for installation of the correct header harness for rain sense.
Added to 2016 Ram 1500 Express with upgraded mirror/harness, MTC to ATC conversion.
Parts List:

Black Vinyl (Having had the problems with the perforated frit and air in those areas, I might mask off the area and use an enamel paint in the future.)

Codes for AlfaOBD in BCM:
VehConfig 2-Rain sensor Present
CustSetMenu 1 Rain sensitive wipers CSM
Side note: I did notice in the new setup for Alfa that there is a 2014 section in the last third of the list of the BCM. Under there I noticed "Rain Sensor Module #2 Present". I did not set this of course but I'm not sure if earlier trucks would need something more???
For whatever reason, I did not have to run the Light Rain Sensor Calibration (for new light/rain sensor module) or the Light Rain Sensor Re-Adaptation (for windshield replacement).
Installation:
The factory location of course cannot be utilized due to the frit, so you have to move the sensor to the passenger side below the dot matrix frit in the upper corner by the mirror. The plug for the rain sensor is short, so you will have to free it up a little and clear it from the rest of the harness. I tried adding some black vinyl to give it as close to factory appearance as possible but as you will see in the pictures below I did not judge my distance very well. This will be redone at a later date.
The lens kit and sensor have to be mounted low enough below the frit and for the height of the wiper. This is why behind the mirror at the factory location is the best spot but I wasn't springing for a new windshield.
I still need to separate the rain sense harness portion from the main harness so it will drop straight down.
My poor measuring for vinyl and also air in dot matrix area of frit.
Instructions for lens/sensor kit general sensor info and sensor installation. You will receive these when ordering the above kits/pads. Mark from GGGCorp was a huge help and gave some much needed insight into the workings of the sensor and their kit I purchased.
Thank you to everyone involved and to @Chach for supplying some great pics which really helped in seeing what the mounting plate (lens) looked like.
If you have any questions, I'll do my best to answer!
Thanks
