Hey cool! What model do you have? Is it one officially support by Volvo for the tow hitch, or no?
I explained more in the other thread, but the used module does not likely have to be matched to the car. The problem probably lies elsewhere, if we can figure it out. There could be a software that needs to be loaded, say if it differed per model and the used TRM came out of a different model than yours. I think that's not likely but just some starting things to think about to check on.
Now that you have installed a new module, run the "Update profile" in OrBit, that will add the TRM module to the car profile. It will then show up in the ECU list on the "ECU Tools" tab, and you can start browsing the "Read data by identifier" for the TRM and see what data you can read from the module that might give a clue why it's not working.
What config item(s) did you change? I can do a little research to see if there is anything special needed for this.
