2018 V90CC - Use OrBit to Add/Program a Hitch CTRL Module?

[Sodertalje]

I'm 99% sure Orbit config change alone is not enough, you also need to make sure TRM has the correct software loaded.

Correct. When you have a new TRM module, you need to load software first using Vida. A used TRM may work, but it's a hit and miss.
