I did not know it took a module, I knew you had to get the sensors but thought it was already set up.
The 2019s are missing the required module. It’s unknown at this point if it will be possible to add on.
The 2020s (according to Ram at this time) will have the module already installed. The truck should also come with a bag of 4 TPMS sensors for you to install in your trailer tires.
