Guess it all depends who did the installation and where the module is mounted. It has to be between the under seat connections to the rear of the bike on the left side.
I got a feeling its between the left tail light and the lower saddlebag plastic.
Mine is where I posted the pics Link to hitch and module.

Yeah, I just don't see a module in there. Before I rip the whole backend apart looking for it, I'm going to look under the seat for it. Tomorrow.
