I have the same set up. It sounds like his H3 didn't come with the tow package. I am not an expert but I wonder if he could find an H3 that does have the package and trace the harness back and see where it connects to the main wiring. It maybe that he could buy a factory or after market harness that would hook right in. I bet the connection is there somewhere.
