If you purchased your Prodigy P3 Trailer Brake Controller # 90195 new, it will have a wiring harness that comes with it that you will have to hardwire into your 2009 Hummer H3.

Otherwise, if you are simply looking for a replacement harness for the controller it is the Replacement Brake Control Plug-In Harness for Tekonsha and Draw-Tite Brake Controller # 20127.

I have added a link to a video review of that harness as well as the Prodigy P3 Trailer Brake Controller # 90195.
