I found a wiring diagram for the factory tow wire harness. It looks like power for the trailer left-turn-signal goes through Fuse 46 (15amp) and into the "Relay - Trailer Tow - Left Turn". The relay is controlled by the Front Control Module. The diagram shows all these inside the Integrated Power Module and I don't know if these are serviceable or if you need a new IPM. The IPM is pretty expensive so you want to be sure before replacing it. I hope this helps you some
