Gettings and Merry Christmas, I recently purchased an 03 GMC Sierra 1500. It did not come with a tow package. Is there a harness that can be plugged into the distribution point near the spare tire? Also, will I need to install a trailer brake module, and if so what is my best option?

Thanks for all replies.
